We started “Music Raygun” with a topic at least one of us has encyclopedic knowledge of. That one of us is Kirk, and the topic is Prince. We don’t talk about only Prince, but also some of the artists and groups associated with him. And there are many. The Purple One had his fingers in a lot of pies. (Sorry.) Our discussion ranges from Prince’s early years to rare television appearances to acts like The Time and The Family to some unusual Prince covers.
