is the first beasties live appearance i've ever seen. and the one i've prob seen the most. back to 1987 and i saw that the beasties would be on this random late-night show i've never heard of while scanning the tv guide. I was 14 years old and stayed up to record the 3 performances on the family VCR.
it was joyous. they performed rhymin' and stealin', no sleep till brooklyn, and half of fight for your right until the let the crowd up on stage. they all looked a little drunk in retrospect. but still young and awesome.
i probably watched that VHS tape a zillion times back in the day.
