In 1985 Josie discovered her love for comedy improvisation quite by chance. She was playing the part of a manic-depressive Glaswegian housewife in a rather dark play at the Donmar Warehouse and, for a little light relief, she decided to stay on one evening to watch the late night show. She had never seen anything quite like it before - a group of mad people led by Jim Sweeney and Steve Steen, all just making the show up as they went along. Josie joined in the next week and the rest is improvisation history!

She joined the Comedy Store Players in 1986 and still performs with them now - playing to packed audiences every Wednesday and Sunday. In 1987 she appeared on Who's Line is it Anyway? And completed seven series of the show. Her proudest moment was improvising with the late, great Peter Cook.

Her own Tv show for Channel 4, JOSIE, was a "cocktail of monologues, sketches, long plays, short films and chat". Each episode ended in an improvised song because they couldn't be bothered to write a theme tune! JOSIE was written by Josie, Paul Merton, Arthur Smith and John O'Farrell.
