Sir William Connolly CBE is a Scottish retired comedian, actor, musician and television presenter, and currently an artist. He is sometimes known by the Scots nickname the Big Yin. Known for his idiosyncratic and often improvised observational comedy, frequently including strong language, Connolly has topped many UK polls as the greatest stand-up comedian of all time. In 2022 he received the BAFTA Fellowship for lifetime achievement from the British Academy of Film and Television Arts.
Connolly's trade, in the early 1960s, was that of a welder 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 1971, 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.
