One of the comments on YouTube said she had a voice so husky it could pull a dog sled. This is one of Julie's biggest hits and she's accompanied by her husband Bobby Troup and his Quintet. It's safe to say this is the definitive version of that song and probably always will be. She aces it. Here's a performance in color and it comes in tight on her beautiful face and doesn't get too far back.

That's where I first saw her when I was a kid and I had no idea she was a sultry singer from the 1950s and 60s until later. Her album covers are quite the thing.
