Does anyone know the piece of music in the background of the YMCA commercial? The commercial features the Rev. Martin Luther King, Jr., in which he is shown going back in time, thru his life stages and careers (from civil rights leader to reverend and finally to his childhood at the 'Y'). The music is the sound of a boys chorus. The melody of this piece is moving and haunting at the same time...I would appreciate anyone's help in finding it's name and/or artist! Thank you!
