For the ones that dont know Spanish, this concert supposedly will feature Brian (it doesn't say anything about Roger though) along with other Spanish performers.
Perhaps this is sort of a tie in with the musical in Madrid.
Another thing, why 46664 concert in Spain!?
According to Brian's page its unconfirmed. link
Oh dear imagine Ricky Martin and Chayanne with Brian! LOL I'd be cool seeing Puerto Rican artists performing with Brian, but Christ I'd cringe! LOL
