I'm sure Ray Agee, that well known Rhythm and Blues artist, walked in to the studio and announced....
"Hey Guys, let's make a different kind of record this session, I've heard that this thing called 'Northern Soul' is going to become massive in Mill towns in the North of England, let's give that a try, eh?"
Or maybe, just maybe, he recorded a R&B record, that happened to fit the template of Northern Soul,
I know where my money lies.
