Although the tape is marked as 21 May 1984 - nothing exists on the tape from this show. In fact it has the missing last 25 minutes from the 16 April 1979 show! The rest of the tape is ambient noise, some promo tracks (presumably the original contents?) and then a brief snippet of Capital FM!

(blank) - black shell
A large proportion of this tape seems to be ambient noise around a train station culminating in a female voice singing 10 Green Bottles?!!
