On 10 October 2009 Jamie Stewart re-joined his former band mates from The Cult onstage at the Royal Albert Hall, London to perform "The Phoenix" and "She Sells Sanctuary" as a second and final encore to a live performance of their 1985 album Love.
Stewart currently lives with his wife and family in Oxfordshire. He has been vegetarian since 1985, and became a Christian in 1998. His amplifier is on display at Hard Rock Cafe Toronto.
