Queen’s chief roadie, Peter Hince, reveals on the book “Davd Bowie I Was There” that there is more material from Freddie Mercury and David Bowie, except from “Under Pressure”. Actually, a few months ago Brian May also confirmed the existence of material, which might be released at some point: “Not all of what we did in those sessions has ever come to light – so there’s a thought”. There’s stuff with Freddie and David singing together. Proper full-length rock ’n’ roll tracks. Raw, but good”, revealed Hince, to the Guardian. Roger Taylor had invited Bowie to Montreaux from his home in nearby Vevey, and the artists’ “mutual admiration” led to the recording sessions. “They just started knocking things around,” Hince remembers. “They did cover versions, a few of their own things. They came back the next day and recorded what eventually became ‘Under Pressure.’ But there were other things recorded which were never finished or mixed. David did vocals which ended up not being used. So somewhere there is an archive. I was in the studio with them. It was all quite spontaneous. I can categorically say I know that there were complete tracks. Not mixed tracks, but fully formed songs. Does it belong to the David Bowie estate or to Queen? That’s probably part of reason these things have never come to light.”
