Ray Castoldi has been the stadium organist at Madison Square Garden since 1989.
He is the only person to play for the Mets, Rangers and Knicks in the same season.
(Gladys Goodding played organ for the Brooklyn Dodgers, the Knicks and Rangers in the same year; likewise Eddie Layton and Jack Shaindlin played for the New York Yankees, Knicks and Rangers in the same season.)
He was also a music director for the ice hockey competition at the 2006 Winter Olympics in Turin, Italy.
Castoldi also wrote Slapshot, the song that is played after the Rangers score a goal at Madison Square Garden.
