Suspect that Tony Higgins is fighting a lone battle with Universal, Roger. Clearly, from his great sleeve notes on the 'Impressed' compilations he's well and truly into this stuff in a very big way. Second your comments about the 'Will Power' reissue. That's exactly how a Brit jazz reissue should be done. Big thumbs up to Vocalion. 'Will Power' is indeed a sleeper in the pantheon of rare but very good British jazz.
Incidentally - and after all these years - I've just been lucky enough to get myself a vinyl 2LP set of it to go with the CDs. It's in the mail..
