I just ran across your posting. The show was on Showtime in 1982 and filmed at Caesar's Palace in Las Vegas. I did tape it and it's quality today is average.
If interested, I would sell it to you for $20, including shipping.

I'm also interested in the same video. Since you are willing to sell a copy of this. What is your address so I may send you my purchase information and get a copy from you. We recorded it off the TV but with time it has gone missing. Thank You.
