When Sandy Denny died in 1978 it was one of the greatest losses English folk music ever suffered. She was only 31, but she’d already contributed to Fotheringay and before that to Fairport Convention, two of the best traditional English music bands of the time. She’d released four solo albums after she left Fotheringay. Her voice was superb, and her songwriting was as well. Her most famous song is almost unquestionably this one, performed first by Judy Collins even before Denny herself had a hit with it. She died tragically of complications from a bad fall down a stone stairway.
