That's really helpful Yank - thanks. I will go and look for those albums for the liner notes if I can. I was sure, for example Ooh, It Hurts Me, that I heard it first via one of the Kent's and yet Outta Sight released it as a 45 which confused me because of those albums you've listed, but then I wondered if I heard it played somewhere before I left many blue moons ago, which got me to thinking was it ever released as just a demo ..................... and so on. When you have songs written, produced etc and that sound as good as these from a group which quickly faded away and with such a pedigree of singers, getting some good background info becomes all the more interesting, not just who was who, where & how they formed etc, but also why they were ever recorded and then their songs sat in the vaults unreleased (and so on).
I read a lot of autobiog's of groups etc to help get an idea of the world of recording artists, managers, producers, songwriters, music lawyers etc, but they don't always give the reasons (other than money) for recording so much material that then was never released. My perception I know is slightly skewed from so many decades now of Northern and what that means to me, how lucky I am to have had the chance to hear such greatness.
Thanks again Yank
