I found this on the interwebs and I wish I knew the band's name! They did a cover for "Get Back" from the Beatles, and it's amazing.
According to the YouTube video, the band performed on a New York City rooftop on September 9th, 2009. The performance was reminiscent of The Beatles' rooftop performance of the song on the roof of Abbey Roads Studios.
If anyone happens to know the name of the bad, could you fill me in?!
