Timothy Lewis – best known by the stage name Thighpaulsandra – is a Welsh experimental musician and multi-instrumentalist, known mostly for performing on synthesizers and keyboards. He began his career working with Julian Cope in the late 1980s, becoming a member of Cope's touring band. A collaboration with Cope in 1993 followed, forming the experimental duo Queen Elizabeth. In 1997, former Cope guitarist Mike Mooney invited Thighpaulsandra to fill in for the departing Kate Radley on a Spiritualized tour, and he remained with the band until early 2008. In 1998, Lewis also became a member of the experimental band Coil. He has subsequently released several solo albums under the Thighpaulsandra moniker.
