I've tended to be a bit mixed with classical music, liking some bits and not getting on with others although I've probably taken to more as I'm older. My mother and I are quite different musically, her being classically trained piano and me trying to play jigs, reels etc, on mandolin, etc. as well as a bit of "folk guitar".
Intro over, I do remember being taken to a couple of things in Llandudno as a child.
One was seeing the WNO do the Barber of Seville at the Astra. I'm generally not that fond of opera, tending more to say Gilbert and Sullivan but I have to say that the whole spectacle was rather good! And I'd still be able to tell you where Largo Al Facotum comes from...
The other was hearing John Ogden play in the Arcadia. I never followed up from there but thought he was quite brillaint.
Outside of Llandudno but staying in North Wales, I also had the pleasure of hearing John Williams in St Asaph cathedral.

Total drift but Ian, (not that I can sight read) I notice a clef by your name. Apologies if I've missed something in my haste to post but do you play an instrument using the alto or tenor clef?
