Yep, MidMichigan Music. Rick Allen owned it. He was a good guy. Was somewhat acquainted with his daughter; haven't talked to either of them in many, many years. Rick eventually closed the music store. Think the big box and online places put him out of business. Used to like going in there just to browse and shoot the breeze.
He still owns the building, though. Where the music store used to be is now a pizza shop, a distillery and a wine shop. He also built out a loft on the second floor, but last I looked the rent was, ah, a bit much.
