Regarding the Chaz Chase short that was this morning's video link: Jerry Beck confirms my hunch that the musical track on it is not an original from 1928. For one thing, "Merrily We Roll Along" wasn't written until 1934 or thereabouts, and "The Merry-Go-Round Broke Down" wasn't written until 1937. Jerry sez the track on the Chase short we watched was lifted from a 1946 short, and he knows this stuff.
But that was basically Chaz Chase's act: He came out and ate things, including his own clothes. In his full act as I remember seeing it, he ate a whole pack of lit cigarettes and matches, then belched smoke for about five minutes. I have no idea how he did this.
I remember that Johnny Carson had him on at least once and a quick search of the incomplete database of Carson guests shows that Chaz Chase was on The Tonight Show on May 17, 1974. The other guests that night were Vincent Price, Bert Convy and Joan Rivers. I recall Mr. Carson being quite thrilled to have him on and making some remarks about how even Chaz wouldn't eat at the NBC Commissary.
