So, I'm not a noob to the Portnoy train, and I've followed most (almost all) the treks off the beaten paths. Listened to the interviews on Trunk and Used Bin, stuff like that, followed the "Q&A's" he used to do pretty regularly, etc. etc.
But I've found a question that I'm sure had to have been asked at some point, but I can't recall (nor find) the answer.
The Cheers theme song, "Where Everybody Knows Your Name" was co-written by Gary Portnoy, from Long Island, born 1956 (he also performed on and sang the song). He was already an established writer, having written songs in the '80's for Dolly Parton, Glen Campbell, and Air Supply. He's also since put out several solo albums.
Any relation?
