'Big Nigel', Fionn, thought that where I was from was somehow relevant to the situation.
Considering that a fair percentage of the people at the gathering were from somewhere else other than there, I thought it relevant to the situation to mention to him that it was irrelevant to the situation as to where I (and by association, 90% of that room) was from.

As for 'cutting across' other musicians playing..., no one seemed to give a good God damn about it happening all the way up to that moment, from all corners.
'Big Nigel' probably weighed up the arguments for and against, did the sensible thing, and withdrew from the situation.

People get their noses put out of joint for one reason or another in sessions, Fionn.

Where I come from, sessions were used to pass music on from one to another. It's what was done to me by some incredibly magnanimous souls, when I was cutting my teeth in sessions as a kid, and it is what I naturally do when in the presence of able and willing musicians, myself, the 'Big Nigels' of the World notwithstanding.

As for egos, Pete, I didn't have anything to prove, and you don't know me well enough, anyway, to be able to make that judgement.

I wasn't going to bring this up, Fionn. So you can congatulate yourself bigtime, here.

I also noticed you never introduced yourself.

Well done.
