Does anybody know if tapes of either of these shows exist? Also has anybody seen either show, if so why did they fail so fast?

I don't know if tapes of those shows exist but I remember seeing both of those shows in reruns on BET. I only saw Sanford Arms once and I only saw half of the episode. It got cancelled quickly because of low ratings, (without Redd Foxx and Demond Wilson the magic was gone.) I use to watch Sanford. I probably saw every episode to that series. It also had low ratings.
