In the 1970s, Adams also recorded roles with Gilbert and Sullivan for All. These were complete recordings of "Trial by Jury" and "Cox and Box", and excerpts (as much as would fit on two sides of an LP record) of seven others. He also made two recordings of lesser-known Sullivan music. With Charles Mackerras and Welsh National Opera's Gilbert and Sullivan series, begun in 1992, Adams recorded the title role in "The Mikado", the Pirate King in "The Pirates of Penzance", Dick Deadeye in "H.M.S. Pinafore", and Sergeant Meryll in "The Yeomen of the Guard".
