It might have been an interview done at WFUV (Fordham University in New York) with Pete Fornatale, somewhere in 2000 or 2001. He kicked off the interview with "I'll Tag Along" - dedicated it to someone in the control room, I think - and it was awesome, just the man and his guitar. Lovely. Alas, it is not in their archives - I just checked in hopes that it might be there.
