3. The Travelling Wilburys
We'd imagine many classic rock fans had to change their pants when the line-up for this supergroup was announced in the late '80s. Made up of Bob Dylan, Roy Orbison, George Harrison (The Beatles), Jeff Lynne (Electric Light Orchestra) and Tom Petty, The Traveling Wilburys came together to record a B-side for Harrison's "Cloud Nine" album. When Harrison's record company heard the resulting track, "Handle with Care," they deemed it too good to be a one-off and requested the band make a full-length. The group obliged, releasing their debut album, "The Travelling Wilburys Vol. 1," to commercial success in 1988 with the members credited under pseudonyms, all relatives of the fictitious Charles Truscott Wilbury, Sr. Orbison's death later that year would spell the end of the original line-up, but the remaining members would release the less-successful "Traveling Wilburys Vol. 3" in 1990 before disbanding forever.
