Some musical collaborations seem downright odd when you first try to visualize the pairings: David Bowie and Bing Crosby (they performed a Christmas song, "Peace On Earth/Little Drummer Boy" on Crosby's 1977 TV Christmas special); Elton John and Dolly Parton (a duet on the CMA Awards show in 2005); Lou Reed and Metallica (they recorded an album together in 2011.)
And then there are those that had "dream team" written all over them from the start: The Beatles and Eric Clapton ("While My Guitar Gently Weeps" in 1968); Michael Jackson and Paul McCartney ("Say Say Say" in 1983); Traveling Wilburys (George Harrison, Tom Petty, Bob Dylan, Jeff Lynne, Roy Orbison).
Classic rock collaborations in 2013 have fallen somewhere between the two extremes. Some crossed genre boundaries, some reunited old friends, some were a little surprising. Here are my favorite five:
