In the 2 years since I became an organ owner again, I've been regularly attending 2 organ clubs in my area - North East Organ Society which meets on the last Wednesday of the month in Birtley (near Chester Le St) and the North Tyneside Electronic Organ Society which meets on the second Wednesday of each month in Killingworth, North Tyneside.
In my time I've enjoyed concerts by Tim Flint, Brett Wales, Tony Fenelon, Chris Powell, Clair Greig and many others playing Wersi / Yamaha (although sadly not the AR - too heavy I should think) / Technics / Bohm. As Hugh mentions in his post these venues / dates and schedules are all listed on OrganFax.
Both clubs are struggling for numbers and will fold if numbers continue to fall. If you can support your local organ clubs - It's a cheap night out and many of the artists are amazing.
I'll get off my soap box now before I fall.
Thanks
Les White
