what is the accordion music played at parties in Klink's quarters and in town on Hogan Heroes episodes? Have never been able to come up with who made the recordings, really would like to find them. Usually featured accordion and guitar

Did some digging one time and came up with the accordionist Frank Marocco, but that is not definitive. Thought it might be Myron Floren from the Lawrence Welk Show, but that's just a hunch. Bob Crane was an accomplished drummer, and the show seemed to put an emphasis on quality background music in general. Albert Ruddy was one of the creators and is still alive at 92
