Sandy Denny possessed one of the most hauntingly pure singing voices of her generation. She released a string of highly regarded folk albums with Fairport Convention, while classic rock fans undoubtedly remember her best from a duet on "The Battle of Evermore" which made her the only guest vocalist ever to appear on a Led Zeppelin album.

Denny died on April 21, 1978, just weeks after falling down some stairs and hitting her head on concrete. Her husband had left with their daughter due to the singer's substance abuse; Denny was discovered unresponsive while staying with a friend. She died days later from what doctors termed "mid-brain trauma."
