"Christmas In Hollis," Twenty Years Ago

The culture (and TV) experts at ego trip bring us a wonderful ghost of Christmas past. Run-DMC, performing one of the very best Christmas songs ever by anybody, on TV, in 1991. It’s a bit mysterious (as most ghosts are, I guess), because no one seems to know what program this was on. Does anybody recognize the backdrop? Chevy Chase’ show didn’t come on til ‘93.
