Oscar-winning singer/songwriter Glen Hansard was the unassuming guy singing the heartbreaking, emotional cover of David Bowie’s classic “Ashes To Ashes” at the makeshift memorial in front of the late legend’s New York City apartment building tonight (Jan. 12) just after 8 p.m.

Few members of the crowd of Bowie fans gathered there to mourn his recent passing realized the talented busker playing the impromptu cover was actually Hansard. “I just wanted to come and play one song for David,” the Irish singer/actor and frontman of The Frames said quietly and gently when several people asked for an encore after applauding.

As snow began to fall on the Soho street, Hansard soon zipped up his acoustic guitar and went off into the night.

Hansard, who won the Best Original Song Oscar in 2008 for the song "Falling Slowly" from the movie Once (which he co-starred in), has been tweeting extensively about what David Bowie meant to him since the icon died on Sunday.

Countless other renowned musicians, actors, producers, and stars from every corner of the globe have also shared tributes to Bowie in the two days since his death. Paul McCartney, Brian Eno, producer Tony Visconti and Lorde were among the artists who wrote or spoke movingly about him. Earlier today, Red Hot Chili Peppers bassist Flea unveiled a Bowie tattoo on his arm, via social media.
