OK, for the birthday girl (65 today - EASY!): This singer/songwriter well-known for her morbid stage fright wrote and performed her biggest career hit in late '72, a month after marrying James Taylor. It is about a self-absorbed lover whose identity is STILL the subject of great speculation (Mick, Warren, Cat, Kris, David - we might NEVER know!). #1 for 3 weeks in '73. #72 on Billboard's Greatest Songs Of All Time. Artist? Song?
Yesterday's answer: Miguel Rios' "A Song Of Joy (Himno a la Alegria").
