It's a little unclear exactly why Steven Tyler, Weird Al Yankovic and Alice Cooper all found themselves onstage in Maui on New Year's Eve, but this video provides irrefutable proof that it happened. Alice has to read the lyrics off a cheat sheet, but Tyler obviously knows the song cold – and Yankovic definitely knows his Beatles. Word is that Tyler also did "Sweet Emotion" at one point, but it was a tremendous lost opportunity for Weird Al to bust out his "Livin' On The Edge" parody "Livin' In The Fridge" with Tyler. (Sample lyric: "If you can name that object in that baggie over there, then mister you're a better man than I.") Weird Al summed up his feelings about the summit in this Tweet: "Every New Year's Eve for the rest of my life is gonna suck."
