Adrian,

Thank you for your frank and honest reply.
It's a debate that will always go on and on and i'm pretty sure your fans will come and see you whatever and whenever.
Box offices are always inundated with enquiries and request (i know i work in one) and sometimes you know the answer you give won't supply the caller with the solution they require, particularly if tickets have sold well.

To be honest i don't mind standing if the artist, band, act, suit it and i reckon a 10 piece band are going to make a pretty big noise.
But as you say venues should make provision for the less able and as a priority not an afterthought.
