“Dick Clark’s New Year’s Rockin’ Eve” celebrated its 40th anniversary Saturday night (Dec. 31) and one of the big stars on hand to perform was teen pop sensation Justin Bieber. The Bieb took on one of the greats – The Beatles.

Sitting at a piano, Bieber plays “Let it Be” live from Times Square in New York City. It’s a rather nice cover of the song, we have to say. Legendary guitarist Carlos Santana also makes an appearance, which is cool.

Lady Gaga was also on hand to perform – she did “Born This Way” and “Marry the Night,” then she got to push the button to make the giant Waterford crystal ball drop at midnight. Happy New Year’s!
