If you mean the main synth (the one during the intro etc), no. It's just one of the pre-set sounds of the Korg M1, and I'm sure because my father's got one.
John hated HS. Fred's fave singer was not PR. Roger didn't compose 'Innuendo.' Witness testimonies are often inaccurate. Scotland's not in England. 'Bo Rhap' hasn't got 180 voices.
