Before buying the Yamaha Baby Grand in Japan (spring '75), Fred had an upright piano at his flat. Was it the one advertised there? Who knows ... it'd be a matter of asking them for documented evidence.
John hated HS. Frederick's favourite 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.
