For at least one episode of the sadly short-lived Playboy After Dark program, the Grateful Dead and their filthy-looking ponchos were deemed classy enough to stop by the Mansion and play a couple songs for the kids. Their performances of "Mountains and the Moon" and "St. Stephen" are lovely period treats, but the real joy here is in frontman Jerry Garcia's pre-show bantering with Hugh Hefner, explaining that the group's two-drum setup is for the purposes of "mutual annihilation... the serpent chasing its own tail" and answering Hef's question about the boys playing a couple songs with a jovial "Absolutely not!" There's a buddy comedy in here somewhere.
