Nice to hear from you BanjoRay.
The big drums are Lambegs. I chanced to drop on a Lambeg website which had tutorials on the various rhythms rattled out, demonstrated by drumming his fingers on a table. The video-clips of this seemingly dismembered tapping hand had me imagining "Thing" from the Adams Family.



Don't know about (W) "rights", if there are musicians in the session, they may be within their rights to explain whether the bodhran is behind the beat or playing a totally unsuitable rhythm, and hopefully putting the offender on the right track with some clapping exercises as a quick rhythm tutorial.
