I think some of the fairs in the Northwest were definitely playing to the growing NS crowd.
I remember loads of popular Motown of the time being played: Two Can Have A Party, Needle In Haystack, Wherever I Lay My Hat etc) but also Festival Time and stuff like The Kid and Condition Red, which sounded awesome coming out of the powerful, bassy systems.
The last two still trigger the sights, sounds and smells of the fairground whenever I hear them.
