If you take a closer look in certain scenes, you can actually see Jackie Gleason's stunt man driving the bandit car from what could have been the original cut of the film. That is the closest thing we are ever going to get from the original cut of the film.
The TV version (which I have) severely cuts all references to sex. Dialog is overdubbed to soften any innuendo. Other scenes in the TV version are alternate takes shot especially. The scene where Junior is talking to the topless girl at the camp is different. She’s wearing skimpy clothes and is not topless. I can only assume that on several occasions they shot a PG friendly version of a scene for use on future TV showings.
