From Rick Sebak's blog: The music for Route 88 had to be piano music.
From Nebby: Rick Sebak's Tales of Greater Pittsburgh:
"The coincidental connection between Route 88 and 88 keys on a piano came to me one morning in the editing room. Then I knew I wanted piano music for the whole program. I guess I was ranting about it somewhat loudly because WQED’s popular TV cook Chris Fennimore happened to be walking by the editing room, overheard me, and he said, 'Call Tom Roberts. He’s a great piano player, and I think he’d like to do this. I’ll send you his info. He’d be perfect.'"
