Elton John Sings Tribute To Prince in Vegas Show

Elton John paid his respects to Prince in front of a sold-out Caesars Palace crowd Saturday night.

Elton paused his 'Million Dollar Piano' show midway to talk about the singer. During his chat, Elton called Prince a "Purple Warrior" and mentioned how the singer was truly one of a kind.

Elton also shared a story about when he and Prince both had Vegas shows ... he said he'd often see Prince in their hotel lobby getting home from the clubs just as Elton would start his day. The singer then went into "I Guess That's Why They Call It The Blues" with a Prince slideshow in the background.
