Bedrock of the Northern soul scene Chris.
All the Top tunes, when I were a lad, were on UK labels.
Of the 30 'Soul Sounds' bootlegs that were done (back in the day) only one (Leon Haywood) had not received a UK release, which highlights their significance.
I guess once the bootlegging think took off, in the early 70's, the only way you'd know you weren't getting ripped off was if you collected British as UK releases were much harder to copy and easier to identify and authenticate.
To some extent, that's still the case!
Besides, as a collector, very few things looks better, to my eyes, than a nice box of Stateside, London American, Sue, Action, TMG's etc. in Black & Silver or Red & White. They always get me salivating to this day!
But my weakness is, I collect everything... and I still get pretty excited even with a box of 'big holes' infront of me!
