Traveling Wilburys. The Traveling Wilburys (sometimes shortened to the Wilburys) were a British-American supergroup consisting of Bob Dylan, George Harrison, Jeff Lynne, Roy Orbison, and Tom Petty. The band recorded two albums, the first in 1988 and the second in 1990, though Orbison died before the second was recorded.
Throughout the '90s, there were rumors of another Traveling Wilburys record in the works, but no new albums from the group surfaced. Harrison and Lynne did re-team in 1995, when Lynne produced and reworked two John Lennon demos with the Beatles for their Anthology rarities collection.
