I have to agree with Tube here Padraic, its your show so pick the dates that suit you. There is no way to please everyone.
Everyone who is available for what you pick will pay up and those that cant will leave a space open for someone else. If it goes well another can be organised in future.
Hoping I can make your dates <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt="
