A Lighter Moment During Convoy Duties - The band of a destroyer on convoy duty, complete even with piano, attracts a balcony audience, including the ship's pet dog, while rehearsing with a choir in a corner of the deck. Although while on convoy duties the crew of a destroyer is constantly on duty there are accassionally lighter moments when the ship's band and choir entertain the crew with music and song.
