I saw a youtube video posted of June Carter (in
rememberance of her passing 11 years ago) She's singing "Raining This Morning" using Jim's band and near the end of the clip at about 3:36 Jim comes in view on the right side of the screen and he's looking around, up in the air, then it appears he lets out a sigh while watching June, he looks bored or perhaphs not impressed with her performance.

Anyway, interesting body language by Jim, here's the clip: https://www.youtube.com/watch?v=E-9_-Pz9WfY#t=222
