Take yer pick... Best for dark late nights of reflection and/or booze. (Only a little booze.)
I heard Betty's version first because ... it's Betty! (+ Betty is finally coming back to this town after a sad long absence following the equally sad closing of Feinstein's in 2012. SarahB and I are seeing her at Joe's Pub in October and I could not be more excited. Nothing is more New York to me than an autumn evening with Betty Buckley.)
And Mary Chapin Carpenter's original... Just unbelievably pretty.
