The Coast Guard didn't get to take the fight to the enemy, but they offered a heck of a musical tribute to their brethren in the Navy in this program conducted in the Hollywood Bowl. Battleships, submarines, flyers and Marines get their songs, as conducted by Rudy Vallee. He also also sings "All the Nice Girls Like A Sailor" with a close-harmony girl trio.
The Coast Guard also gets its own song at the end, although I think they could have done a bit better for the first line in the century and a half between their founding and this short. Bobby split his time in this period between being a dance director and directing short subjects like this one. Alas, it was his last. He died on Leap Day in 1944, only 46 years old.
