Steve, I think if an organisation (whether a band or a dance club) takes affiliate membership then it is covered for its own activities. So for a band that would cover playing as a band but not organising ceilidhs, whereas for a dance club it would cover organising dances but not committee members playing as a band. However that's just my own interpretation, best check with EFDSS.

And in reply to Matt's last post, EDFSS aren't being nannyish in asking for evidence of PLI, it's to protect themselves - in case there's a claim against them for which the promoter might be partly responsible, or a claim by them against the promoter, they want to know that he has sufficient financial resources, and isn't what lawyers call a "man of straw".
