He also continued to record, especially with Charles Mackerras and Welsh National Opera, appearing as Sergeant Meryll in the Welsh National Opera production of "Yeomen" 1994–95, the first Gilbert and Sullivan production staged at the Royal Opera House. His last appearance, only a month before his death, was with English National Opera in "Don Pasquale". "The Times", in its obituary of Adams, concluded: "At the time of his death Adams had a diary as packed as any leading opera singer half his age. He was particularly looking forward to a performance in Benjamin Britten's "A Midsummer Night's Dream" at the Metropolitan Opera".
