Geoffrey Alexander MacCormack, better known as Warren Peace, is an English vocalist, composer and dancer best known for his work with David Bowie in the 1970s.
A long-time friend of Bowie since their schooldays in Bromley, Peace (initially as GA MacCormack) contributed backing vocals to a number of albums, beginning with Aladdin Sane in 1973 and continuing through to Station to Station in 1976.
He appeared with Bowie during his 1973 tour of the US and Japan, travelling back to the UK via the Trans-Siberian Railway with the singer, who refused to fly.
With Bowie, Peace co-wrote the music for "Rock 'n' Roll With Me" on Diamond Dogs (1974) and later "Turn Blue" on Iggy Pop's Lust for Life (1977).
With fellow Astronettes Ava Cherry and Jason Guess, and Bowie as writer/producer, Peace recorded an album's worth of material at Olympic Studios late in 1973, which was eventually released as People from Bad Homes in 1995.
