What a throwback! I used to listen to this about 15-20 years ago and it’s how i first encountered “you’ve got possibilities” with Linda Lavin back when it was exclusively showtunes. It was on RCN I think.
It was kinda like Sirius Xm’s Broadway channel minus special programming.
It maybe your current pet peeve but pre-streaming music it was a good way to discover music from shows I hadn’t seen.
