Bass guitar player for the British post-punk band The Cure, 1979-1982 and
1985-present.
After leaving The Cure, Simon formed another band called Fools Dance.
His friend Gary Biddles sang most of the songs released by this band;
Simon only sang one called "The Ring." The band dissolved after Simon
reconciled with Robert Smith and rejoined The Cure.
He is the youngest of six children born to Bob and Peg Gallup; his
siblings are Stuart, David, Duncan, Monica, and Ric.
He has been married twice. His first wife Carol Thompson is the younger
sister of Porl Thompson. They had two children named Lily and Eden before
they were divorced sometime around the end of the Wish Tour in 1992.
Since then, Simon has married a woman named Sarah and had a third child
named Evangeline.
He is the second longest serving member of The Cure, hence he is often
referred to as Robert Smith's right-hand man.
