What is the title for the theme song for the show "Las Vegas" and who performs it?

(The show I'm talking about is on NBC Friday nights)

I'm talking about the theme song on the DVD. I know the theme song on currently is "A Little Less Conversation" by Elvis. The song has the lyric "No guilt, no shame, no pity/You play the game baby in Sin City" It's not on the soundtrack. Please help!
