Background: 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".
Context: Johnny Fean continued to play live music with Stephen Travers, formerly of The Miami Showband.  After his retirement, Eamon Carr went on to become a producer of young rock talent in the mid-1980s, and also forming his own record label called Hotwire (which sponsored noted acts such as the punk rock group The Golden Horde). He also did a number of specialist DJ slots on radio before morphing into a music/sports journalist with the Evening Herald in Dublin. More recently he presented on a Dublin station 'Carr's Cocktail Shack' in which he played American music of the 1950s and 1960s. In 2008, Carr and Henry McCullough co-wrote a new bunch of songs. A resulting album entitled Poor Man's Moon was released on 1 September 2008. Also in 2008, Carr released his first book, The Origami Crow, Journey Into Japan, World Cup Summer 2002, a book that is at once a travel log about his journey to Japan, a poetry collection, an homage to Japanese poet Basho, heralded by many as the creator of Haiku, and also has some sports commentary thrown in.  Barry Devlin directed for the screen and been a drama writer for radio and screen, as can be seen from his credits on the IMDB and for the radio detective drama Baldi He produced a number of U2 videos in the mid-1980s. Examples of his screen writing are evident in the joint RTE/BBC production Ballykissangel and ITV's The Darling Buds of May.
