No Mal, the official site did announce it first and then deleted it the next day before putting it back up again a few days later.
That was long before anything was posted here.
The official site only announces gigs that are actually confirmed.
I bet the poor souls who booked tickets for Edinburgh had waited for official site confirmation now.
I don't know why you'd think people on this site would know about gigs before the people who actually book them do, but my advice would be no matter what you read here, wait for the official confirmation before parting with your cash.
