William C. Ismer is a retired police officer who has found his musical calling in a most unusual place: Tampa General Hospital.

Over the past seven years, Ismer has volunteered to play music for patients -- pop, jazz, classical, whatever. Sometimes he plays hymns. Sometimes country: Willie or Elvis. Billy Joel, the Beatles, whatever the patient might find soothing. He played In the Presence of Jehovah for a mother whose infant twins died at birth. When he played What I Did For Love for a 40-year-old woman waiting for a kidney, she sang along.
