Here's a companion to Seamus's excellent link(before the fire) on page 22 linked here:

In this new one, Lee Perry returns to the burned out Black Ark and muses about various subjects, His attention seems to be drawn to the fuse box that fed power to the Black Ark. On the back porch is Aston "Family Man" Barrett (Bob Marley's bassist) and there is a bizarre exchange as to whether a man or a woman is on top of the "system" and finally he explains that the Ark was a UFO base that is connected with the mother base in Peru near lake Titicaca.
Paul McCartney and Robert Palmer, amongst others, recorded at the Black Ark.
This Vid appears to be from the time period after his first round of fame, but before he moved to Europe for his second reinvention.
