"This picture really defines the relationship with Willie and Ryan perfectly," says Casal. (Adams produced Willie Nelson's 2006 album Songbird.) "Ryan very much looked like the irreverent, cocky punk that he is. He's saying here, 'Yeah I don't care if you're Willie Nelson. Whatever.' And Willie on the other hand is looking at Ryan saying, 'Well, you gotta deal with me.' I think Willie saw a lot of his much-younger self in Ryan."
