During the program, we learn that the album Perspex Island had just shifted into the top position in the US college radio charts. That happened on 1991-10-05 (Saturday). So, I'm guessing that the real date of this program would have been 1991-10-06 (Sunday). It's possible that 1991-10-08 would've been the date of a rebroadcast, so the tape's label would've just been incorrect for the month.
