Sounds exactly like him, he's one of those people who takes himself achingly serious, should have become a lawyer. Colleagues like that always provoke me to constantly take the piss on them. You'd think that someone with his talent and success would be a bit more relaxed about himself, but some people's minds stay small even if they have done great things.
"Don a henley and take it easy ..." - that is not only a harmlessly funny pun, but - save for the pun effect which could have worked with any famous name that is also a product name - it doesn't capitalize on his Eagles fame at all, never mind that he not only did not sing lead on Take it Easy, but that he also didn't write it. It was Jackson Browne (and Glenn Frey). No one is going to buy a "henley" and believe the product has anything to do with (much less is endorsed by) him, I can't believe that Henley's legal case has legs to stand upon.
He must have a bad PR advisor. He should have talked him out of it.
