The all-star cast is set for tonight's Teacher's Rock special on CBS and we get a little teaser of the show from Garth Brooks to get us ready for it.Garth is joining Carrie Underwood, Dierks Bentley, pop group Fun. and Josh Groban tonight beginning at 7pm on CBS. It airs just in time for us to think about our teachers as the kids start heading back to school over the next couple of weeks.

I would like to be one of the first to say thank you to all of our teachers.
