I have no idea where exactly this improvised concert took place. All we know is that Brian May attended the wedding of Felix Taylor and his girlfriend Jo and joined the wedding band for three songs (as he confirmed on Twitter) - with presumably Roger on lead vocals (?). Among attendees were Anita Dobson, Debbie Lang or Jim Beach.
