Antony Genn (born 1971 in Sheffield, England) is a British musician formerly in Pulp.
"The Planets Bend Between Us" (or "The Planets Bend Between Us (For You)") is a song from alternative rock band Snow Patrol's fifth album "A Hundred Million Suns".
 It was released as the follow-up single to "If There's a Rocket Tie Me to It" on 24 May 2009.
 It was the fourth single taken from the album.
 The lyrics were written by Gary Lightbody and the music was composed by Snow Patrol.
 The song is about Lightbody's beach house in Belfast.
 The single featured a re-working of the album version and was released as a digital download only.
 It was later included on the band's 2009 compilation album "Up to Now".
Gary Lightbody (born 15 June 1976) is a Northern Irish singer, songwriter, guitarist and multi-instrumentalist, best known as the lead singer and rhythm guitarist of the Northern Irish-Scottish rock band Snow Patrol.
Rock Art and the X-Ray Style is the debut album by Joe Strummer and the Mescaleros, released in 1999.
 This album featured the band in its first incarnation: Joe Strummer and Antony Genn on guitar and vocals, Martin Slattery playing keyboards and guitar, Steve "Smiley" Barnard on drums, Pablo Cook on other percussion instruments, and Scott Shields on bass.
 Richard Flack also did engineering on the album.
"Just Say Yes" is a song by British alternative rock band Snow Patrol, released as the single to follow "The Planets Bend Between Us" in October–November 2009, depending on the region.
 The song, produced by Jacknife Lee, is one of the three new songs, and the lead single from the compilation "Up to Now".
 The lyrics were written by Gary Lightbody and the music was composed by Snow Patrol.
 "Just Say Yes" has its origins as a song written for pop singer Gwen Stefani, who rejected it.
 Nicole Scherzinger of the Pussycat Dolls was then given permission by Lightbody to record it for her solo debut album, which was later shelved.
The Trip: Created by Snow Patrol is a mix album compiled by alternative rock band Snow Patrol's vocalist Gary Lightbody and released through the Family Recordings label on 1 November 2004.
 Issued as a 2×CD and a 3×LP Vinyl, the album was the fifth in "The Trip" series.
 In the CD release, Disc I was called "Bert" and Disc II was "Ernie".
 Lightbody wished to compile his own "Trip" album after listening to the album compiled by Tom Middleton.
 Lightbody credits his DJ friend Roy Kerr, better known as The Freelance Hellraiser, for putting together most of the songs (which he then picked for the album), joking about directing Kerr "from the comfy chair".
 Lightbody also wishes to compile a similar album with Kerr in the future.
Tired Pony is a music supergroup consisting of Gary Lightbody, Richard Colburn, Iain Archer, Jacknife Lee, Peter Buck, Scott McCaughey and Troy Stewart.
 Lightbody formed the group out of his appreciation for country music, and has during the early planning phase described the group's music once as "country-tinged" but explained later that in the end the album's development turned out much more to Americana than country during the whole creative process in the studio.
 The group visited Portland, Oregon in January 2010 to record this debut album, which was produced by member Lee; "The Place We Ran From" was released on 12 July 2010.
 Tired Pony began recording their second album "The Ghost of the Mountain" on 19 February 2013, which was released on 19 August 2013.
"Take Back the City" is a song from alternative rock band Snow Patrol's fifth album "A Hundred Million Suns".
 It was released as the lead single from the album on different dates in October 2008, depending on the region.
 The lyrics were written by Gary Lightbody and the music was composed by Snow Patrol.
 The song has positive lyrics, and is about Lightbody's love for Belfast.
 The song has been officially remixed once, by Lillica Libertine, and it appeared as a b-side to the single.
The Hours are an English rock band, formed in 2004 by Antony Genn and Martin Slattery.
"If There's a Rocket Tie Me to It" is a song from alternative rock band Snow Patrol's fifth album "A Hundred Million Suns".
 It was released as the follow-up single to "Crack the Shutters" on 8 and 9 March 2009.
 It was the third single taken from the album.
 The music was composed in collaboration between the band members of Snow Patrol, and frontman Gary Lightbody serving as lyricist.
 The song is a departure from Lightbody's frequent attempts at diagnosing his less positive personal issues, which often focus on his romantic breakups, and instead celebrates a newfound love outside human relationships.
