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.
There never was a supergroup more super than the Traveling Wilburys. They had Jeff Lynne, the leader of ELO; they had Roy Orbison, the best pop singer of the '60s; they had Tom Petty, the best roots rocker this side of Bruce Springsteen; they had a Beatle and Bob Dylan, for crying out loud!
