IN: Horslips are an Irish Celtic rock band that compose, arrange and perform songs frequently inspired by traditional Irish airs, jigs and reels. The group are regarded as 'founding fathers of Celtic rock' for their fusion of traditional Irish music with rock music and went on to inspire many local and international acts. They formed in 1970 and 'retired' in 1980 for an extended period. The name originated from a spoonerism on The Four Horsemen of the Apocalypse which became "The Four Poxmen of The Horslypse".

In March 2004, three Horslips enthusiasts, Jim Nelis, Stephen Ferris and Paul Callaghan, put on an exhibition of Horslips memorabilia in The Orchard Gallery in Derry. It was opened by the band, who played five songs acoustically. Buoyed by this first public appearance in 24 years, Horslips returned to the studio in Westmeath to produce a studio album, Roll Back, in the summer of 2004. Described as "Horslips Unplugged", the album contained acoustic reworkings of many of their best-known songs. The same exhibition moved to Drogheda in October 2005, courtesy of longtime fan Paddy Goodwin, and was formally opened on 6 October by a tribute band, Horslypse, composed of nine teenage musicians. Horslips did a version of "Furniture". The exhibition moved to Belfast in February and March 2006 and there were plans for a New York showing in 2007. In February 2008, the exhibition opened in Ballinamore in County Leitrim, and in July it opened in Ballybofey in Donegal. A double DVD entitled Return of the Dancehall Sweethearts came out in November 2005. Disc one is a documentary and disc two was live footage of the band from the 1970s, including promo videos and slots on The Old Grey Whistle Test. In December 2005, the band played in front of an invited audience for the recording of the RTE television program Other Voices in Dingle in County Kerry. Part of the set included three songs done "full-on" - the first time the band had played live and electric since October 1980. The last Horslips' event in this phase of their career was a TG4 tribute show recorded and broadcast live on 25 March 2006 before a live invited studio audience. A number of Irish personalities were interviewed, in Irish, about what the band meant to them and how Horslips shaped modern Irish music.

input: In early March 2008, the duo's second album, The Odd Couple, was leaked over the internet prompting the duo to push the release date up from April 8. In an interview with Entertainment Magazine, Danger Mouse said that he "knew it [the leak] was coming...every day, I expected to get a call saying it leaked, and eventually I got a call saying it leaked." On March 18, 2008, the album became available via download on the iTunes Store and Amazon MP3. Hard copies of the album were released on March 25. Prior to its official release, Green spoke to the album's anti-formulaic qualities, noting bluntly that "there's no formula to it," and that to expect the same wild success of St. Elsewhere is to neglect the ever-present "risk factor in any artistic endeavor." He called it something of an "act of faith" - a true, earnest attempt to create and disseminate a piece of art to those who would seek out its conception. They appeared as the musical guest on the April 12, 2008 episode of NBC's Saturday Night Live. They were supposed to be in a Digital Short parodying amateur music videos according to the scrolled text but only appeared in the singing performances of the live broadcast. On November 11, 2008, they released an EP, Who's Gonna Save My Soul, featuring four versions of the song which originally appeared on The Odd Couple, along with a live version of "Neighbors" and a previously unreleased song, "Mystery Man."
