Dorothy Ann Collins, was an English folk musician, arranger and composer. She was the older sister of Shirley Collins.
Born in Hastings, Sussex, she grew up in an artistic, socialist, folk singing family. She learned the piano at school, and then studied with composer Alan Bush while taking odd jobs in London, including working as a bus conductor. In the mid-1960s she began working with her sister Shirley, who was establishing a reputation as a leading folk singer. She arranged some of Shirley's songs and, on the album Sweet Primeroses, accompanied her on portative organ.
Further work with Shirley followed: Shirley said "You could launch yourself off on a Dolly arrangement." In 1968 they produced the album Anthems in Eden, commissioned by BBC Radio and written for a six-piece early music consort directed by David Munrow, and regularly toured together. Dolly also worked as a musician and arranger with other singers and bands, including The Incredible String Band on The Hangman's Beautiful Daughter, Matthews' Southern Comfort on their debut album, Spirogyra on their third album Bells, Boots and Shambles and Peter Bellamy on the ballad opera The Transports.
