Toni Tennille provided backing vocals for pink Floyd's album The Wall. The Captain was nowhere in sight.
"Weird Al" Yankovic released a single called "Christmas at Ground Zero," way back in 1986.
Lindsey Buckingham wrote nine of the songs on Fleetwood Mac's Tusk album; Stevie Nicks wrote five. Still, Stevie's songs take up more of the original album's running time than Lindsey's.
Donovan and the Beastie Boys are both going to be inducted into the Rock & Roll Hall of Fame next year, which means that the Beasties' King Ad Rock will be forced to share a stage with his ex-father-in-law. Awkward! I'll have much more on the Class of 2012 shortly.
