A fresh take on one of Sia’s most powerful anthems has just been released by Allie Sherlock, and “The Greatest” is a track that is carried entirely by conviction and feeling. This performance has been added to her channel, and a genuine pop classic has been reinterpreted here, one built around a message of resilience that is still felt strongly today. The full performance can be watched below, and the story behind the song is told further down the page.

About This Performance

This cover has been posted to Allie’s official YouTube channel, and it is counted among her more memorable releases. “The Greatest” is a song that is driven by stamina and heart rather than vocal gymnastics, its power is found in sincerity, and that quality is played to well by Allie, a performer who has always been connected to audiences through genuine emotion rather than showmanship.

About the Song

“The Greatest” was released by Sia, featuring Kendrick Lamar, in September 2016 as the lead single from the deluxe edition of her seventh studio album, This Is Acting. The song was written by Sia and Greg Kurstin, who also produced the track, and it was met with strong chart performance internationally, reaching the top five in several countries. Its accompanying music video, in which dozens of young performers are freed from confinement, was widely interpreted as a tribute to the victims of the 2016 Orlando nightclub shooting, even though this was never officially confirmed by Sia herself. Its message is simple but powerful: no matter how much breath is lost along the way, freedom and greatness can still be claimed. That universal theme of resilience is a big part of why the song is still so widely performed and covered today.

Why Allie’s Version Stands Out

The best covers of a song like this are not reinvented, they are meant. Allie’s following was earned by busking on the streets of Dublin, precisely because a song everyone knows can be made to feel personal and immediate by her. A track about stamina and quiet defiance is sat perfectly in that wheelhouse, and this is exactly why her stripped back, voice forward approach to big anthems tends to be resonated with by listeners.

Who Is Allie Sherlock?

Allie Sherlock is an Irish singer and guitarist from Douglas, Cork, born on April 7, 2005. Fame was found by her through busking on Dublin’s Grafton Street, and virality was achieved in 2017 with a cover of Ed Sheeran’s “Supermarket Flowers.” Today her YouTube channel is followed by over 6 million subscribers, and a path has been carved by her from street performances into original music and headline touring across Europe.

Frequently Asked Questions

Allie Sherlock has released her take on “Proud Mary,” one of the most covered and immediately recognizable songs in rock history. This is the kind of track that demands energy and commitment, and Allie brings both. Watch the full performance below, then read on for the story behind the song.

About This Performance

This cover lives on Allie’s official YouTube channel. “Proud Mary” rewards performers who lean into its momentum, and Allie does exactly that. Her acoustic approach strips away the studio production and puts the vocal front and center, letting the song’s energy carry itself on pure delivery alone.

About the Song

“Proud Mary” is a song written by John Fogerty and first recorded by his band Creedence Clearwater Revival. It appeared as a single in January 1969 and on the band’s second studio album, Bayou Country, peaking at No. 2 on the Billboard Hot 100. Fogerty wrote it on the day he received his discharge papers from the army, strumming his guitar in a celebratory mood, with lines flowing out of him almost immediately. The song follows a man who walks away from a steady city job to ride a riverboat called the Proud Mary, finding more life and warmth among people at the margins than he ever did working for wages.

Two years after CCR’s original charted, Ike and Tina Turner released their version for their album Workin’ Together. Their arrangement climbed to No. 4 on the Billboard Hot 100 and earned the duo a Grammy Award for Best R&B Vocal Performance by a Group in 1972. That version, with Tina’s commanding vocals and the famous slow-to-fast build, became the one most listeners picture when they hear the title today.

Why Allie’s Version Stands Out

The best covers of “Proud Mary” don’t imitate either the CCR original or the Tina Turner landmark. They find a third lane. Allie built her following by taking songs everyone already knows and making them feel personal and alive, and a track this kinetic suits that approach well. Her voice-forward performances tend to cut straight to the emotional core of a song, and “Proud Mary” has plenty of core to cut to.

Frequently Asked Questions

Allie Sherlock has just released her take on one of Michael Jackson’s most beloved songs, and “Man in the Mirror” is the kind of track that lives or dies on raw emotion. Fresh on her channel, this is her interpretation of a genuine pop classic, one built around a message that still lands decades later. Watch the full performance below, then read on for the story behind the song.

About This Performance

This cover arrived on Allie’s official YouTube channel on May 26, 2026, making it one of her newest releases. “Man in the Mirror” is a song carried by feeling rather than vocal gymnastics, its power is in sincerity, and that plays straight to Allie’s strengths as a performer who has always connected with audiences through genuine emotion rather than showmanship.

About the Song

“Man in the Mirror” was released by Michael Jackson in 1988 as a single from his blockbuster album Bad. Written by Glen Ballard and Siedah Garrett, it became one of Jackson’s signature anthems and reached number one on the US Billboard Hot 100. Its message is simple but powerful: if you want to change the world, the place to start is with the person looking back at you in the mirror. That universal theme is a big part of why the song is still so widely performed and covered today.

Why Allie’s Version Stands Out

The best covers of a song like this don’t try to reinvent it, they mean it. Allie earned her following busking on the streets of Dublin precisely because she can take a song everyone knows and make it feel personal and immediate. A track about honest self-reflection sits perfectly in that wheelhouse, and it’s exactly why her quieter, voice-forward approach to big anthems tends to resonate with listeners.
