It wouldn't be the first or last time Brian's memory slips.
WWTLF, in the studio, features Brian playing a DX-7 synth and his home-made guitar (or perhaps a replica ... hard to tell as they're 99% identical in sound).
ITtWWC was played live with Roger's Gibson Chet Atkins, but in the studio it was recorded with a 12-string Ovation.
John hated Hot Space. Frederick's favourite singer was not Paul Rodgers. Rog didn't compose 'Innuendo.' Witness testimonies are often inaccurate. Wales is not in England. 'Bo Rhap' hasn't got 180 vox.
