The Carpenters sing "We've Only Just Begun", 1971. Written by the great Paul Williams (and Roger Nichols). Karen's voice is so good that it took a while before I found a version that I was sure was live, only because she played with the lyrics a little.
Karen Carpenter, 1950-1983 She had the best voice. I still sing along to her music. A Mid West girl who made it big and was pressured to lose weight. (She must have been a size 6 at the most.) You're missed Karen!
