Wanted to take some time out today on our series to post a song and some performances with some real staying power. This Ralph McDonald composition is still as vibrant today as it was when it was released some 40 years ago. Of course we begin with a great live performance from 1981 from the artist most associated with this classic: the one and only Grover Washington Jr.!

Ms. Winehouse!

Ms. Flack!

The Philadelphia Experiment!
