I first saw Spike Lee’s documentary, “Do It Acapella” back around 1990 or 1991. In those days, if you saw something on TV, it was gone unless you were watching a channel like MuchMusic that repeated it’s programming on a set (six hour?) rotation throughout the day. In that case, you could set your VCR and get a permanent copy the next time the show (or video or whatever) was aired. (I still have dozens of VHS tapes filled with music videos I compiled by doing this.)
This documentary was shown on PBS (which didn’t repeat blocks of programming) but I was able to get a copy when it was re-broadcast later in the day.
