Though she played WPC Sally Reed in the television series Dixon of Dock Green between 1968 and 1969, she is most familiar from her appearances in the TV commercial for the carpet freshener Shake n' Vac, which was shot in 1979 and ran from 1980 to 1986.
The advert featured Logan dancing around a typical British living room in high heels, shaking the powder onto the carpet and vacuuming it up, while singing a musical jingle.
At the time this advert was being made Logan was in a leading role at the London West End's Cambridge Theatre as Velma Kelly in the first British production of Chicago.
She appeared in Stepping Out, Cowardy Custard, Irene, Annie and Barry Manilow's Copacabana at The Prince of Wales theatre, and a subsequent production in Denmark directed by Craig Revel-Horwood.
She also appeared as a black leather clad policewoman in a comic serial during a run of The Two Ronnies ("The Worm That Turned").
