I agree, Austin. It would take something going catastrophically wrong for them to not follow up.
It sounds to me from Vince's quote in that interview that he is absolutely salivating at the thought of touring with the Eagles. "I always thought I'd have made a good Eagle," he says, all smiles.That sounds like he's ready to make this arrangement long term.
It doesn't sound like he is being billed as a special guest, does it? I really think they are seriously going to make Vince Gill an official member of the Eagles.
