By the way, the leader of this quintet is Henry Kailimai, who penned "On the Beach at Waikiki." Henry Ford caught the quintet's gig at the Hawaiian Pavillion and liked them so much that after the PPIE he hired them to be the Ford Motor Company's house Hawaiian band. They recorded under the name of The Ford Hawaiians.
