Sir William Connolly CBE (born 24 November 1942) is a Scottish actor, retired comedian, artist, writer, musician, and presenter. He is sometimes known, especially in his homeland, by the Scots nickname the Big Yin ("the Big One" Known for his idiosyncratic and often improvised observational comedy, frequently including strong language, Connolly has topped many UK polls as one of the greatest comedians of all time Connolly's trade, in the early 1960s, was that of a welder (specifically a boilermaker) in the Glasgow shipyards, but he gave it up towards the end of the decade to pursue a career as a folk singer. He first sang in the folk rock band The Humblebums with Gerry Rafferty and Tam Harvey, with whom he stayed until 1974, before beginning singing as a solo artist. In the early 1970s, Connolly made the transition from folk singer with a comedic persona to fully-fledged comedian, for which he is now best known. In 1972, he made his theatrical debut, at the Cottage Theatre in Cumbernauld, with a revue called Connolly's Glasgow Flourish. He also played the Edinburgh Festival Fringe. In 1972, Connolly's first solo album, Billy Connolly Live!, was produced, with a mixture of comedic songs and short monologues.
