I have the vinyl for "They Said It Couldn't Be Done" (two copies in fact). It's actually pretty good. The accordionist is Dominic Frontiere, better known for his TV and film scores, including "Hang 'Em High" and music for "The Outer Limits."

Trivia: Paul Winchell is the father of April Winchell. http://www.aprilwinchell.com/audio/
