Saw this Old Navy commercial during SPN last night and HAD to find the song! It's by Son Of Dave and called "Revolution Town". Pretty soon I was listening to more of his songs. He's got a song called "Hellhound". Oooh! Boy! Would that make a great song for SPN! The one called "Shake A Bone" is great as well. Awesome, energetic, gritty, bluesy stuff! Love it!!!
Here's the commercial (love seeing such amazing athletes/dancers/acrobats!):
