Single on A&M by Los Angeles band of singer-songwriter Emitt Rhodes, formed 1966 after he left British Invasion-oriented band The Palace Guard.
The Merry-Go-Round released several singles 1967-68 and an album (1967) on A&M before disbanding in 1969.
After The Merry-Go-Round, Rhodes went solo, playing all the instruments on a self-titled album that he recorded in a studio he built at his parents' house. Emitt Rhodes (1970), reminiscent of The Beatles (especially McCartney), was well received and is regarded as a major work of the 1970s. Other albums followed in the first half of the 70s before he went into producing and engineering, although he has released further material in recent decades.
