He's a LOT precious . He's been performing for many many years and he knows what he's doing for the best, not only for himself in order to give the best performance , but to protect the audience, and make sure they get what they paid for , and NOT have the occasion spoilt by a hard core of so-called fans, who can be noisy (generally after imbibing too much ) and use his gig ,(and other Irish performers)an excuse for a gathering of the Irish "Clan"/hangers on , and a good piss up.
Christy puts first things first i.e. YOU the audience , so admire him for it and stop these snidey references.
There are performers who maybe deserve criticism for their inability or unwillingness to interact with the audience - Christy ,is certainly not one of them.

Cheers ,
