The previous 6 releases on "It's Soul Time" over the last 14 years are all still available and I'm guessing had similar size small runs. Why this one blew up, who knows, the crazy world of Northern Soul eh?
Simplistic I know, but I think of Northern Soul as a Tamla Motown / Funk Brothers based rhythm, and what we now call Modern Soul based on the B-H-Y and MFSB rhythm section at Philadelphia International Records. Just my individual opinion
