William Fitzsimmons (born 1978) is an American singer-songwriter, based in Illinois. He is perhaps best-known for his songs "Passion Play" and "Please Don't Go", which aired during pivotal scenes in the TV medical drama Grey's Anatomy. Fitzsimmons was raised in the outskirts of the steel city of Pittsburgh, Pennsylvania, the youngest child of two blind parents. Due to the family's inability to communicate through normal visual means, Fitzsimmons' childhood home was filled with a myriad of sounds to replace what eyes could not see.
