Pat Green's brand new single out to radio, Girls from Texas, is flying up the charts. Well, now the legendary singer/songwriter is participating in the Down Syndrome Association of Central TX 2015 calendar.

Green also took the time to encourage all of his fans to get involved with a charity, in some form or another. He says "I'm not saying you have to support my causes... But support a cause of your choosing. Paying it forward with your time is way better than with your money!!"
