The script held in the Crawford Collection in the AFI Research Collection includes the following character notes (excluding regular characters):
'CHEEKY CHARLIE: 65. "Cheeky Charlie" had been a fairly well known Tiv personality at the time of "Mo", George Wallace, etc.
'When Charlie started to slide (through a combination of T.V. and the bottle) he and his assistant, Bluebell [sic] took to the road. Charlie put on the occasional show for the kids, including punch and judy [sic] and tuned pianos when he could get the work. He deludes himself that he could always stop drinking the moment he felt like it, but blames the lack of $100 or so to get new costumes and a good, reliable agent. Then, he says, he can make his big come-back.
