I have accepted an offer to add an additional UK date after London; we shall be playing at The Assembly in Leamington Spa, England on March 2nd.  I believe this will now be the final date on the European tour and I don't expect any more cities to be added.
The Zealots' pre-sale has been posted on the store and will include a Zealots-only Q&A with Eddie before the show, at 5:30pm.
For the North American fans who are hoping to see UK's Final World Tour, there is the growing possibility of one or two shows; but nothing is confirmed.
