Daryl Frank Dragon (August 27, 1942 – January 2, 2019) was an American musician, known as Captain from the pop musical duo Captain & Tennille with his then-wife, Toni Tennille.
Born into a musical family, Dragon was the son of Eloise (Rawitzer) and conductor, composer, and arranger Carmen Dragon, and the elder brother of Dennis Dragon, a member of the 1960s pop combo The Dragons and the 1980s surf band the Surf Punks. His godfather was actor and comedian Danny Thomas.
In late 2009, Toni Tennille announced her husband had developed familial tremor. According to Tennille, his condition was neither debilitating nor terminal. Rather, his noticeable tremor was exacerbated by stress and anxiety. Subsequently, the tremor condition limited most of Dragon's public appearances. In November 2009, Toni Tennille announced that Dragon was under a physician's care to determine the best method of his treatment.
In September 2010, Tennille publicly clarified her husband's condition as "a neurological condition (later confirmed to be essential tremor), which causes him to have tremors". Tennille indicated the condition was debilitating to Dragon's abilities as a musician.
Essential Tremor is a neurological disease that causes a rhythmic trembling of the hands, head, voice, legs, or trunk, the largest movement disorder in the world, affecting over 100 million (including children). ET is a progressive disease and can worsen with time causing serious debility. It can begin at any age and doesn’t discriminate with age, race, sex, or national origin.
