re the official credits - with the (uncredited) exception of 'Shades of Rock' studio album they were a 'four piece' band from Jet Harris days up until John Farrar left in 1976, thereafter a core trio of Hank, Bruce and Brian....accompanied by 'sidemen'
therefore despite the sterling longtime service of Alan Jones, Mark Griffiths, Paul Westwood, Alan Tarney, Dave Richmond, Mo Foster,etc...and a few others too, they all would appear along with keyboardist Cliff Hall, and synth' player Dave Lawson etc to be 'sidemen' playing with the core Shads trio of Marvin-Welch-Bennett (& Farrar in Alan Tarney, Dave Richmond & Mo Foster case) - tho' we of course would regard them all as being 'Shads'
as 'official' actual Shadows members (even if employed by the band) the bass players were only Jet Harris, Brian Locking, and John Rostill (while Alan Hawkshaw was an 'official member' Shadows keyboardist over 1968-70)
Thus the late Great John Rostill was the longest 'official' band member Shadows bass player from late 1963 up to 1968
- after the 1968 break up the all important bass guitarist role was never again an 'official' part of the core band - various bass players featured on 'Shades of Rock' in 1970 (Herbie Flowers was one I think) tho' the sleeve bore no credits
when they reformed as The Shadows in 1973 John Farrar was 'the fourth man' in the core band but while an official Shadows member he was of course guitarist/keyboardist/vocalist (tho' he probably played some bass too) & arranger, while from that point on the bass player was then credited as a 'sideman' (Alan Tarney on RWCL) and became a figure who was not included in group photos on albums etc
and that's official ! lol
