They woulda been The Partridge Family if the producers hadn't wanted to fire their mom and replace her with Shirley Jones. Susan is still making records and playing gigs. John is playing drums in the Beach Boys Band. I have a great Dwight Twilley MTV concert where Susan and John are in the Twilley Band (Susan & Dwight were a couple for many years.) I opened for the Cowsills at Maxwells in the early/mid 90's and they were great. Susan signed my poster "Spike will you marry me" (!).
I guess one of the Cowsills married a Playboy Bunny... The Cowsills-Playboy After Dark.mov
The first song is pretty corny ("Jesus Christ Superstar" I think) but they really rock out on the 2nd tune. Susan is an ultra hip dancer.
