I agree Stigweard when you say "...I think musicians can talk as long as it's not intrusive, or is on the fringes of the group..." I also think it's OK for singers to do the same. I sometimes talk but when I do I am very sure to keep the noise down and try always to be aware of what is going on around me, it's just a case of good manners and respect.

However, I don't think you can tell none musicians and singers (the general public) to shut up because a pub is a pub and the louder you play or sing the louder they will talk. Instead use it as a tool to your advantage. When there is noise hone in your concentration skills and this will help to shut out those making the racket. I used to have a problem but quickly taught myself to ignore them. Now I find that I can concentrate quite well on what I am doing if it's a solo or on what others are doing who join in. It's quite easy with a bit of practice and it enhances the enjoyment because after a while you don't notice others chattering.
