Contacting them is a good idea but it is not enough.
The uk folk scene needs more events organised, preferably by people who are intersted in the music for the music sake, rather than by agents, IMO the music should be organised with the ideal of making a small profit which is then put back to cover any future losses
this is how the folk revival started, the EFDSS offers its members insurance for organising events. it is up to members to get up and orgasnise just one event in the year
