It seems that movies about muscicians never seem to be all that interesting. I got to see JC and June about two years before he died. He was much better in person than on record. And physically large; he is a big guy; but that wasn't the real site; his band is made up of guys bigger than he is; his bass player looks to go over 300 lbs easy. Now you put them next to June who is about 4'11" and it is a comical site. She looks like a little kid on stage with them. But what a voice; pure as the driven snow. Cash has a much deeper baritone voice that doesn't come across on recordings; and much more lively and interesting also. I guess he comes from a time when singers had to be good; you couldn't hide in the mix.
