Jack's Mannequin

Jack's Mannequin is a project of Andrew McMahon, who is the vocalist, pianist and main songwriter of the band Something Corporate. The name Jack's Mannequin originated from one of McMahon's songs called "Dear Jack", which was written about a friend of his whose brother was diagnosed with childhood leukemia. Andrew himself was diagnosed with leukemia on June 1, 2005 and cancelled a show for the first time ever when he received the call from his doctor.

Everything in Transit, released in August 2005 received a positive response from fans and critics alike. A summer tour was scheduled to support the record release, but was canceled after McMahon was diagnosed with acute lymphoblastic leukemia and had a bone marrow transplant.      source=last.fm
