VIDEO : Lady Gaga's Cover of John Lennon's 'Imagine' is Stunning

Imagine Lady Gaga singing John Lennon's "Imagine,". She did just that during the European Games opening ceremony in Baku, Azerbaijan.
Gaga, who is one of only two female artists this decade with three No. 1 albums (the other being Taylor Swift), performed the 1971 classic on a piano covered in flowers.
Gaga memorably veered away from her pop-music background to showcase her jazz skills by singing with Tony Bennett. The duo's jazz album, Cheek to Cheek, debuted at No. 1 on the Billboard 200 in October.??
