Flo and Joan are an English comedy music act consisting of sisters Rosie Dempsey (vocals, percussion, electronic drums, recorder) and Nicola Dempsey (vocals, piano, recorder). The act generally consists of comedy songs the sisters have written themselves, that blend elements such as alliteration, political humour and observational comedy. Their stage names are taken from their grandmother and her sister.
Flo and Joan have been featured on BBC One's Live at the Apollo, Stamptown Comedy Night and the Off Menu podcast, amongst other media. In 2018, they were featured in a Nationwide Building Society television advert. They released an Amazon Prime Video special, Alive on Stage, based on their Edinburgh Fringe show in 2019.
In 2024, Flo and Joan wrote and composed One Man Musical, about Andrew Lloyd Webber. They appeared themselves as backing musicians, with George Fouracres starring as Lloyd Webber.
The sisters grew up in Portsmouth, lived in Toronto for a few years, and as of February 2019, now live in London.
