"if people as average as me can get a reaction as good as that"

Yeah - me too - I was in Eisteddfods as a youngster, and I know how good I was relevant to the very best around then (many others were far better!) - and I'm out of practice these days! :-)

Yet, I can still pull off a 'show', funny though, it's actually EASIER for me to do it with a big crowd than a small one!

Yes, if I focus and get a chance to rehearse up to speed, I can do - as my dad used to say - a passable attempt and be listenable, and even con some into thinking they enjoyed it! And, the sad thing is - it's not (so it seems to me - at least, even the practice is enjoyable!) all that much work, oh pardon me, does that mean I have some ... shudder... 'natural talent'... or did I just put in years of hard work decades ago.... :-P

So if I mutter under my breath about the relative level of others' performance skills, maybe I do know a few tricks... not that I think I'm all THAT good...
