Grimethorpe Colliery Band is a brass band, based in Grimethorpe, South Yorkshire, England. It was formed in 1917, as a leisure activity for the workers at the colliery, by members of the disbanded Cudworth Colliery Band. It achieved worldwide fame after appearing in the film Brassed Off, and along with Black Dyke Mills Band, the band became the first to perform at the Proms.

The year after the band's formation saw it enter its first competition at Belle Vue in Manchester. Its first radio broadcast was in 1932 and from 1941 to 1951 was on UK national radio every month.

George Thompson was musical director from the early 1950s until 1972 during which time the band won the British Open Contest for the first time. Thompson was followed by Elgar Howarth as Professional Conductor and Musical Director. 1974 saw the band, along with Black Dyke Mills Band, become the first to perform at the Proms.

The band continued through the industrial troubles of the 1980s and the closure of Grimethorpe Colliery on 13 October 1992. However the band gained first place with 99 out of 100 on 17 October 1992 in the National Brass Band Championship at the Royal Albert Hall in London.

Following the closure of the Grimethorpe Colliery in 1993, the Band was sponsored by RJB Mining (later UK Coal plc) and then by Powerfuel.

Grimethorpe Colliery Band has premiered some of the most important brass music of the 20th century, including Sir Harrison Birtwistle's Grimethorpe Aria, written for the band, and Hans Werner Henze's Ragtimes and Habaneras as well as several pieces by Sir Malcolm Arnold.

The band has appeared on rock and pop records, notably "When an Old Cricketer Leaves the Crease", on Roy Harper's 1975 HQ album, and Peter Skellern's 1978 and 1979 albums Skellern (including the hit single "Love Is the Sweetest Thing") and Astaire.

International fame came with the film Brassed Off, the plot of which was based on Grimethorpe's struggles against pit closures, and whose soundtrack was recorded by the band. The band also performed Ron Goodwin's film score for the 1976 Disney film Escape from the Dark (also called The Littlest Horse Thieves), with the composer conducting. They also recorded some of the Beautiful South's hits in the 1996 and the tracks were given as extra tracks on the cd single issues. Wikipedia
