One of the most beautiful songs ever recorded
My own preference by a very slight margin is the Sarah Vaughn version, but both are unbelievably great.
Written by pianist Erroll Garner in the early 50s, and originally recorded by him without vocals. Here he is on the Ed Sullivan Show in 1961.
Pure beauty.
Imagine, if you can, being so good at singing, and voice control, that you can sing that melody.
