Tom Petty has recently done a interview with Classic Rock Magazine (Read it here). In the interview Petty talked about The Travelling Wilburys, the supergroup he was part of alongside George Harrison, Bob Dylan, Jeff Lynne & Roy Orbison.
The band came about due to Harrison needing a B-side for This Is Love. The song which came about Handle With Care was deemed far too good for a simple B-side by the band. So they decided to form The Travelling Wilburys (A recurring joke of Harrison's).
In the interview Petty said "That extra track turned into the Travelling Wilburys. It was a wonderful time. There was never a negative moment doing that. We really enjoyed that. I think we made that record for us really"
"Those 10 tracks were all we did. We'd go and cut the track. We'd have to dinner, and work on the lyrics over dinner, and then go to do the vocals - Bang. I love those guys" said Petty. The Band released two albums Vol 1 & Vol 3.
