Alexandra Elene MacLean Denny was an English singer-songwriter who was lead singer of the British folk rock band Fairport Convention. She has been described as "arguably the pre-eminent British folk-rock singer/songwriter of her time". After briefly working with the Strawbs, Denny joined Fairport Convention in 1968, remaining with them until 1969. She formed the short-lived band Fotheringay in 1970, before focusing on a solo career. Between 1971 and 1977, Denny released four solo albums: The North Star Grassman and the Ravens, Sandy, Like an Old Fashioned Waltz and Rendezvous. She also duetted with Robert Plant on "The Battle of Evermore" for Led Zeppelin's album Led Zeppelin IV in 1971. Denny died in 1978 at the age of 31 from head injuries sustained as a result of a fall down a flight of stairs. Music publications Uncut and Mojo have described Denny as Britain's finest female singer-songwriter. Her composition "Who Knows Where the Time Goes?" has been recorded by Judy Collins, Eva Cassidy, Nina Simone, Mary Black, Kate Wolf, Nanci Griffith, 10,000 Maniacs, Luke Sital-Singh and Cat Power.
