Kirsty Anna MacColl (10 October 1959 - 18 December 2000) was a British pop singer-songwriter. She was the daughter of dancer Jean Newlove and noted folk singer Ewan MacColl. MacColl began her career in the late 1970s UK punk rock scene, singing backing vocals for Drug Addix. She was probably most recognizable in the United States as the writer of "They Don't Know". Tracey Ullman's version, helped by a video guest-starring Paul McCartney, reached Number 2 in the UK in 1983 and the Top Ten in North America.
