I've always thought Sandy Denny was quite beautiful, with a voice to match her looks.
And she played guitar and piano in addition to singing and writing songs. She was with Fairport Convention, The Strawbs, Fotheringay, had a solo career, and was the only guest vocalist to ever sing on a Led Zeppelin studio album ("The Battle of Evermore" on Led Zeppelin IV.)
If I had to choose an all-time favorite female vocalist, it would probably be Sandy Denny.
Sadly, she died a tragic death at the age of 31, in 1978.
