There are certain songs that become anthems. They are timeless and cross all genres of music. The kind of song that every single person you know has at least heard of. Waylon Jennings and Willie Nelson hit number one with one those types of songs 40 years ago today when the classic "Mamma's Don't Let Your Babies Grow Up To Be Cowboys" went to the top of the charts.

I, like most country music fans, can sing every single word to this bad boy and am about to do so now. Join Willie, Waylon and myself and we sing one of country music's all time greats. Enjoy!
