Okay.. I've tried searching for various things and cannot find it here or on the intertubes.

I'm looking for the name of a band. Two girls and a guy, I think, doing sort of 1940s style music. One distinct feature of the clip was that the two women are leaning forward when they both sing into the same microphone.

Gah. That's such a crappy description. But it's all I can put to words.
