Random Quote

“Oh, the happy choir director who is hired to start work on a brand new choir, or who walks into his first rehearsal a total stranger to the existing group—what a fortunate man he is! The new choir director who is a former member of the choir, or a member of the congregation, or the nephew of the alto soloist, or a former altar boy, or otherwise well acquainted with the choir, is in for a few headaches.”

— Paul Hume (1956)
