"Hapa-haole" is the more proper name for what most 20th century Americans would think of as sung Hawaiian music, where the tune, styling, and subject matter have very distinct Hawaiian elements, but the lyrics are mostly in English. It became sung by both Hawaiians and contemporary performers, such as the Bing Crosby vehicles "Sweet Leilani" and "Blue Hawaii" in 1937. Alfred Apaka was arguably the foremost interpreter of hapa haole music, melding Hawaiian music with traditional American pop arrangements and English lyrics. Apalka began touring in the late 1930s, and settled more into routine shows at performance rooms created just for him in Hawaii in the 1950s. He would also sing at large luaus being put on by Donn Beach.
