I remember those two doing the rounds during Stafford, Rod...mind blowing stuff! I also got an acetate around that time from Ady Pountain of 'Sugar...' backed with 'Come On Back...' resplendant with fake photocopied labels waaaaaaay before Paintshop made life easier!
The Soussan guide book has a load of Motown acetates in it, including Suspicion, as featured above.
Anyone got the listings for the two tapes just to jog my memory, please?
