39. Terry Bradshaw "I'm So Lonesome I Could Cry" (1970)
Bradshaw's job was completing passes for his team and the other team (his TD-INT ratio is 212-210), and winning Super Bowls, not making songs. Bradshaw does one of the most robotic performances of Hank William's classic ever seen. And what's with this quarterback always shaking his head just when he's about to hit the high notes? We hope that's not a medical condition.
