Sad about the news of Tom Petty's passing. I was nothing more than a casual fan, but I always enjoyed his music, especially his tribute to Brian, Hung Up and Overdue, which appears on the great soundtrack he did called She's The One which also features Carl on background vocals.

FYI, there's a Petty thread in the General Music portion of the board.
Speaking of BB connections, the first track of his 1999 Echo album "Room at the Top of the World" is apparently a tribute to Carl Wilson who'd passed the year prior.
