no Jim, its not that i dont like it, as i said I do like unaccompanied singing, but rules like that it exclude.
I understand why they have that rule, I am aware of at least two clubs that have that rule, I tell you why i think it is amistake.
1. it is exclusive.

So is just having singing. They could have tunes too.

So are the sessions I go to. One is pretty strict on no songs and only allows tunes you'd find in an Irish repertoire.

We could have everything as a free for all and anything goes but I believe the scene (in my case UK) would be weaker and poorer for it.

There is plenty of room for people to go to more general and more specialised events or perhaps do both - you don't have to be one or other. It's not hard to find what suits you best out the events available to you and there is always the possibility of starting something else should nothing fit the bill.

The only way I can see a problem is if people were going around insisting that every event operated in the same way. This is something I've never encountered.
