It is true the guitar lines on Joe Frazier are reminiscent of Holdsworth. This, however, doesn't imply that Holdsworth had been a member of the band at the time that tune was introduced. There was little in John Clark's style during his tenure in Bruford that wasn't clipped from Holdsworth. However, Clark's playing showed skill and musicality, if not originality, and GGT was better than most would have supposed a Bruford/Stewart/Berlin record sans Holdsworth to be. Note that "Land's End" may be the best National Health track ever, and it's not even National Health.

It's mostly that one section where the guitar lead hits, where it sounds like it should have one of those reverb-drenched stacked contrapuntal melodies like in "The Abingdon Chasp."

Then again, I may be misremembering something here, because there might be something sort of like that on Jeff Berlin's updated solo version. I only have that on vinyl, though, so I can't check.
