Agreed re Mr Whithorns playing... I think I still have a Crawler white-label or tape somewhere that had him playing Kossof stuff exceptionally well... There was a pick-up band I've mentioned elsewhere called Chuck Farley, which had GW on guitar, along with Boz Burrell on bass, the last time I saw them they had Chris Slade on drums... the next time I saw CS was with "The Firm"... a link below...
http://www.chuckfarley.co.uk/I think I still have an LP of privately released material, resplendant with autographs for it's plain white cover...
Another semi linked band I liked were called Zzebra, which contained a couple of guys from If and a chap called John McCoy, who, of course, went on to Gillan - Zzebra were a jazz-rock outfit that also fused African rhythms (psst, Bret... don't let Uwe know I used the "F" word...)
Trying to remember another pickup band he played and recorded with, maybe with Rory Galagher's bass and drums (Rod De'Ath), in the 70's... one lp was called "Live, a week at the Bridge" (LP + 12") a bunch of people playing at an East London pub - some of it was exceptionally good - the bars main claim to fame was that Iron Maiden played there a lot in their early days...
