Interesting topic. Without the early pioneers like Levine or Soussan, would countless others have followed, crossing the pond to track down the records at source? Without the interest from UK collectors at that time, certainly kindled by Levine and Soussan, wouldn't a lot of this "unwanted" vinyl have found its way to landfill, thus denying others the chance to discover it at a later date? Obviously the archived stuff in the record company vaults would remain, but how long would the Northern Soul scene have lasted if solely reliant on British releases and the odd import?
