Peter Moon was born on the island of O’ahu to Wook and Shay-Yung Moon. From the late 1950s through the 1960s, he gained musical inspiration, insight, and knowledge; playing as a Maile Serenader with Gabby “Pops” Pahinui in the 1960s. Later, in the 1970s, he also served as Gabby’s manager. Soon after, Moon became a founding member of The Sunday Manoa, along with Palani Vaughn, Alfred “Baby” Kalima, and Cyril Pahinui (one of Gabby’s sons). After Vaughan and Cyril left the group, Moon released another album (Hawaiian Time) with Alfred and another of Gabby’s sons named Bla. After this however, Moon remained the only member and recruited the very young Robert and Roland Cazimero. In 1969, their first album, Guava Jam was released and became seen as the spark of the Hawaiian Cultural Renaissance. Two more albums were released, but personal conflicts within the group led to their eventual breakup.
