I Had An Amplifier, Too

 

I just really like the verse:

From across the canyon a guitar plays
Through an amplifier on long delay
It was an old melody, I recognized the song
I had an amplifier, too, so I played along…

It sounds very friendly.  Full lyrics HERE.

Backup Band

 There have been at least four albums where Tom Petty and the Heartbreakers were essentially the backup band for somebody else:

• The Missing Years by John Prine
• Unchained by Johnny Cash
• American III:  Solitary Man by Johnny Cash
• Mystery Girl by Roy Orbison

They also backed up Joe Cocker on a Rick Rubin produced album, but Joe hated it so much that he bought back the master tapes and never released it.  (I'd still like to hear it.)
