Great finds Bill!
Wish I knew the name of the movie from the 3rd clip. My guess is that it was a porn flick from the early 80's. The joker with the thick hair and beard who is 90% naked (ugh) appeared in another porn flick from the 80's featuring women boxing. It was titled "Back Street Alley Cat," and featured future wrestling star Linda Dallas as one of the topless boxers.
The clips from the Hindi movie were exceptional -- far better than most Bollywood productions.
