NKIT - In my opinion, he did talk more easily about Glenn though it looked like the emotions were still right there below the surface. In the above story about songwriting, he looked a little reflective/wistful when he spoke of first writing with Glenn. Or at least that is how it looked to me - like he enjoyed remembering how he and Glenn could be totally honest with each other.
And again to me, he was beaming and once looked like he was on the verge of tears when he talked about Deacon and what a fine job he did in LA and how proud his dad would have been of him. The emotion was clearly showing then.
