In 1966, he and other musicians from the Boston folk scene formed a group called the International Submarine Band. After briefly residing in the Kingsbridge section of the Bronx, they relocated to Los Angeles the following year. Following several lineup changes, the band signed to Lee Hazlewood's LHI Records, where they spent late 1967 recording "Safe at Home". The album contains one of Parsons' best-known songs, "Luxury Liner", and an early version of "Do You Know How It Feels", which he revised later in his career. "Safe at Home" would remain unreleased until mid-1968, by which time the International Submarine Band had broken up.
