I think John Mac was only in the Jet/Tony backing group for a short while, playing rhythm while Joe Moretti playing lead.
I don't think he was in Jet's backing group on the 1964 NME concert..although I can't remember whether that group was the Jet Blacks or the Innocents
(Joe Moretti evidently played on the recordings of Scarlett, Applejack, and possibly Song of Mexico after Jet left. He maintained he stepped in upon request when Jet was indisposed at that time, and that the money offered to substitute (and to say nothing!) was needed by him at the time.)
John Mac was evidently playing with quite a few groups as well as sessions back then, and he also worked in a London music shop, selling guitars- and practicing like mad when business was quiet...building up his amazing technique.
All of the top session guitarists on the scene at that time (Jim Sullivan, Joe Moretti etc) were in awe of him, evidently, and they all said he was THE best of all of them. some said they couldn't believe he was only playing rhythm when he was so talented- but I suppose he was scratching for any work to make money to survive back then...
