Jack's Mannequin's power pop sound evokes shades of the Beach Boys and classic Elton John.
Jack's Mannequin creator, Andrew McMahon, is also in the band Something Corporate.
Diagnosed with leukemia, Andrew underwent chemotherapy and a bone marrow transplant. His sister was the bone marrow donor.
The name was inspired by the song "Dear Jack," which McMahon wrote about a friend's brother who was diagnosed with leukemia.
McMahon also contributed two songs to Tommy Lee's 2005 solo album, "Tommyland: The Ride." Find all your favorite Jacks Mannequin ringtones and Jacks Mannequin realtones below.
