Great song! I'd forgotten how much fun that song--and, indeed, the whole show--was, but the Kennedy Center production, while not very good, really pointed up what a great book and score that show has. I also have the DVD of the cast recording session--Donna McKechnie, Pamela Myers, and Susan Browning had to do ten takes of that song to get it right. Can you imagine?
I've never heard this radio show, any recording of Side by Side by Sondheim (I'm not normally a fan of revues), or the German cast recording of Company, but it definitely sounds pretty interesting.
