To be honest, Willie Nelson doesn't do a whole lot on stage, but he does it all right – photographically speaking. And having been around as long as he has, it's no surprise that Willie Nelson is a pro in front of the camera.
First, he uses spotlights. He's lit up like a living legend (which, of course, he is). He allows photographers up close and personal for three solid songs. Despite constant vocal duties, he takes time to step out from behind the microphone for every song. He points, he gestures and he waves.
Now, these are all really little things in the scope of the whole performance, but what they add up to is that they make Willie Nelson photograph fantastically. Total pro.
