 He served as the lead guitarist, co-lead vocalist and principal songwriter of the English rock band Oasis.
 Raised in Burnage, Manchester, Gallagher began learning guitar at the age of thirteen.
 After a series of odd jobs in construction, he worked for local Manchester band Inspiral Carpets as a roadie and technician in 1988.
 Whilst touring with them, he learned that his brother Liam Gallagher had formed a band of his own, known as The Rain, which eventually took on the name Oasis.
 After Gallagher returned to England, he was invited by his brother to join Oasis as songwriter and guitarist.
Siouxsie and the Banshees were an English rock band, formed in London in 1976 by vocalist Siouxsie Sioux and bass guitarist Steven Severin.
 Initially associated with the English punk rock scene, the band rapidly evolved to create "a form of post-punk discord full of daring rhythmic and sonic experimentation".
 In 1978, they released their critically acclaimed debut album, "The Scream", and built their reputation over the next few years through subsequent releases.
 With "Juju" in 1981, the group also became an important influence on the emerging gothic rock scene.
 They disbanded in 1996, with Siouxsie and drummer Budgie continuing to record music as the Creatures, a second band they had formed in the early 1980s.
 In 2004, Siouxsie began a solo career.

 Written by guitarist and vocalist Noel Gallagher in 2001, the song was originally recorded for the Oasis album "Don't Believe the Truth" in 2004, but was removed from the final track listing.
 When the band released a compilation of the same name, it was rumoured that the song would appear as a bonus track on the album, but as of 2009 (and the disbandment of Oasis) the song remained unreleased.
 A studio performance of the song, believed to be dating from the "Don't Believe the Truth" recording sessions, as well as a live version performed in May 2003, were leaked onto the internet on 6 May 2008 by an Oasis fansite.
 On 6 July 2011, it was announced that "Stop the Clocks" would finally be released on Noel Gallagher's debut solo album, "Noel Gallagher's High Flying Birds".
