Context: "Rebuild" is a song written by Jon Foreman of Switchfoot and Matt Thiessen of Relient K.  The song was written in conjunction with the bands' 2007 Appetite for Construction Tour, featuring members from all three bands on tour, Switchfoot, Relient K, and Ruth.  Thiessen sang second vocals, and Dustin Ruth of Ruth played harmonica. Matthew Arnold "Matt" Thiessen (born August 12, 1980) is a Canadian-American musician, singer and songwriter known for being co-founder, lead singer, guitarist, pianist, and primary songwriter for the Christian rock band Relient K.  With Relient K, he has released eight full-length albums, including three that were certified Gold, and three that peaked in the top twenty on the "Billboard" 200.  Outside of his work with Relient K, Thiessen maintains a low-profile side project called Matthew Thiessen and the Earthquakes.  In 2009, he co-produced and collaborated on Owl City's album "Ocean Eyes". "My Girlfriend" is a song by the Christian rock band Relient K, released on their self-titled first album.  The song originally appeared as "Marilyn Manson Ate My Girlfriend" on the band's demo album, "All Work and No Play".  The song is about Marilyn Manson eating Matt Thiessen's girlfriend.  Thiessen wrote this song when he was 15 years old.  Thiessen has said that he wrote it because of a female friend, who lived eight hours away in Pennsylvania, who he would talk to about many things including spiritual matters such as where God was taking them in the future.  His friend would later turn from Christian music to Nine Inch Nails and Marilyn Manson.  In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.  Thiessen would later state "She felt that Christianity was stupid and just this big hypocrisy.  Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson." Stephen Peter Marriott (30 January 1947 – 20 April 1991) was an English musician, songwriter and frontman of two notable rock and roll bands, spanning over two decades.  Marriott is remembered for his powerful singing voice which belied his small stature, and for his aggressive approach as a guitarist in mod rock bands Small Faces (1965–1969 and 1977-1978) and Humble Pie (1969–1975 and 1980–1981).  Marriott was inducted posthumously into the Rock and Roll Hall of Fame in 2012 as a member of Small Faces. Marriott is Steve Marriott's debut solo album from 1976 and features a British and an American side, reflecting the make-up of the bands backing Steve Marriott.  The British side includes former Humble Pie colleague Greg Ridley on bass and singing backing vocals. Matthew "Matt" Henshaw (born 10 September 1987) is an English musician, singer, and songwriter.  He first emerged in 2010 as a soul singer collaborating with numerous artists, cited as the NME Breakthrough Artist and compared to Smokey Robinson, Curtis Mayfield, Marvin Gaye and Al Green.  He has often cited his influences to be the likes of Sam Cooke, Otis Redding, Steve Marriott and Steve Winwood. Go for the Throat is the tenth studio album recorded by the English rock band Humble Pie and the second with the new lineup including, guitarist and vocalist Steve Marriott, drummer Jerry Shirley, American bassist Anthony "Sooty" Jones and vocalist and guitarist, Bobby Tench from The Jeff Beck Group.  Marriott also brought in backing vocalists Marge Raymond, Dana Kral and Robin Beck, once again looking for a more authenthic and refined R&B sound and feel.  "Go For The Throat" was released by Atco in 1981 and the new version of "Tin Soldier" reached #58 in the US single charts.  A promotional tour started but was curtailed after Marriott damaged his wrist and shortly afterwards suffered from a duodenal ulcer. Humble Pie were an English rock band formed by Steve Marriott, in Essex during 1969.  They are known as one of the late 1960s' first supergroups and found success on both sides of the Atlantic with such songs as "Black Coffee", "30 Days in the Hole", "I Don't Need No Doctor" and "Natural Born Bugie".  The original band line-up featured lead vocalist and guitarist Steve Marriott from the Small Faces, vocalist and guitarist Peter Frampton from The Herd, former Spooky Tooth bassist Greg Ridley and a seventeen-year-old drummer, Jerry Shirley. Steve Marriott All Too Beautiful is the official biography of Steve Marriott, the singer, guitarist and frontman of the Small Faces (1965–1969) and Humble Pie (1969–1975). The following list details musicians who have been members of the English rock band Humble Pie.  The original lineup consisted on Steve Marriott, Jerry Shirley, Greg Ridley and Peter Frampton.  Frampton left the band in 1971 and was replaced by Clem Clempson who remained with them until the band broke up in 1975.  Since 1975 there have been a number of reformations of the band including various original members and additional musicians.  Between 1989 and 1999 original drummer Jerry Shirley obtained the rights to the band's name and began performing with new musicians, and Steve Marriott's blessing, as Humble Pie featuring Jerry Shirley.
