I wonder if they've sorted that out for the re-issue?
Acording to Dave Gelly's article the sound is much improved, so this CD version sounds like a 'must have'.
I'm trying to think who was in the 'Major Surgery' reunion at Swanage way back. The late Tony Marsh was on drums I think but not sure of the rest of the band.
There have been some good articles in Jazz Journal of late. Much improved magazine.
