Carly Simon's leonine purr and soaring delivery grace a huge range of collaborations, covers, and more. Back in the '60s, she and sister Lucy playfully harmonized on the folk fairy tale “Winkin', Blinkin' and Nod.” Her duet with former brother-in-law Livingston Taylor on the orchestrated ballad “Best of Friends” is truly touching, while a sensuous take on “Ev'ry Time We Say Goodbye” is one example of her mastery of the Great American Songbook.
