Queen and David Bowie’s “Under Pressure” is an iconic classic for both artists.  But Brian May has hinted that more Queen/Bowie collabs might be lurking in the vault. In a recent interview, May said they would play “all sorts of old songs” during those recording sessions, including covers of Cream’s “N.S.U.” and “I Feel Free”. While they were never released, May says those old recordings may be in the archives somewhere.
