Mari Wilson (born Mari MacMillan Ramsey Wilson, 29 September 1957, in London), is an English singer, best known for her sometimes quirky, early 1960s influenced pop music songs, and her (former) trademark beehive hairdo. She enjoyed six chart hits in the UK in the early 1980s, performed with jazz bands, and sang the theme-song to the TV sitcom Coupling, "Perhaps, Perhaps, Perhaps". She has also performed in musicals, and has been a feature on a BBC TV series about celebrities and their health (she has Type 1 Diabetes).
