I am beginning to believe that it is us that is crazy.

Thanks for your support. However, I think that I may have given you the wrong impression.

I also find it difficult to believe that you have to be a union member to sing in public. (I am a union activist here.)

That is not the case. It was just that on that day the MU had organised the event and hired the bar (to prevent problems to the licensee) for a publicity stunt. The MU considered that the musicians there (other than Billy Bragg) were just not really required. It was their party after all.......
