20 Feet From Stardom: Da Doo Sing, Sing

Chances are you've never heard of them. But you have heard them.
They're the Rayettes, the Harlettes, the Supremes. The backup singers that "Oooo" and "Mmm," and "Da Doo Ron, Ron."

Now they have a documentary of their own.

The music, and there's plenty of it, is the best part of this film. But it's also an interesting subject. Who are these people and why are they always, well, twenty steps from top billing?

It turns out some of them are just fine with their position on stage. And others are still hoping for star billing.

This is a must-see-and-hear doc for anyone who loves popular music from the 1950s to today.
