What rock band/song is the bumper music that CBS has been using during Dal/Den game?

It's sorta a catchy up tempo song that was on the charts about a year ago. They keep playing the intro to it at different segments. Thanks.

Black Betty. Originally done by Ram Jam, back in the '70's. Redone this year or last. Not sure who by.

The song is Black Betty by Ram Jam. At least that is the song they just played during the intro to the 2nd half. The same song was used in the movie Blow.

Edit: I must type slow.
