Stevelotm's setlist.fm

This pretty reliable website does list them as playing Dudley that night. Maybe they two shows on the same date but in any event I am not going to delete it unless we get confirmation that the Dudley show didn't happen.

Re: Tattoo The Planet 2001, thanks for the info.

Most users don't provide sources when they add or edit setlists, so it can be tough to track down the correct information.

I didn't add the HRH United festival, so I can't say why it was added the way it was. If it's wrong, you can report it here and we'll fix it:
