I think the delle haensch tracks heard in Gumby are probably from the cbs ez cue library….
The Conzelmann/Hanesch music was mostly likely distributed at the time by the same unknown library Clokey got a lot of mileage of in the later 60s shorts - one probably ran by Gene Kauer and Doug Lackey, as their names are attached to several cues on ASCAP heard on Gumby as well as Davey and Goliath.
