This is based on the song "Music For A Found Harmonium," which was originally written by Simon Jeffes for the jazz collective Penguin Café Orchestra's 1984 album Broadcasting From Home. Apparently Jeffes composed the track on a harmonium he found abandoned on a Tokyo street. The version this song is based on was by Irish Band Patrick Street, who made it into a rollicking Irish reel. It originally featured on their 1989 album 3 Irish Times 3 and the track went on to be featured in a number of movie trailers and television commercials.
Steve Mac (real name Steve McCutcheon) is one of the most successful British producers and songwriters of the last 20 years, having credits on over 40 #1 singles and albums for artists such as Westlife, Gareth Gates and Leona Lewis. This marriage of a traditional Irish reel with techno beats was his first solo release though in the early 1990s he had a number of hits as a member of the house act Nomad and the pop/dance trio Undercover.
This song prompted a craze with people dancing to the song in the most unlikely of public places and uploading the resulting videos to YouTube.
