If anyone's interested there's a 14 minute interview with John Reed (formally of Sanctuary Records) about the Cherry Red box set catalogue covering eveything from 60s psych sets on Grapefruit to 80s indie collections on Cherry Red on their website here:
Well, it's mainly about 80s comps actually but there's all the 60sbox sets spread over the table to salavate at! I think what they actually discuss, how these comps are put together etc is as relevant to any of them anyway, well worth a watch.
