Joni Mitchell, just caught her singing at the Gershwin Prize broadcast March of last year. She would have been 79. I have not heard her sing since the 70's, she is fat now, but it sure hasn't hurt her voice, did a rendition of Summertime and The Circle Game, velvety butter-smooth voice, she definitely will never require pitch correction, absolute perfect pitch. Still has her beautiful long blonde hair, but her voice has only improved through the years.
