Dio confusion

A few sites seem to be reporting a forthcoming DIO gig in Dublin on May 10th at Temple Bar Music Centre, prompting calls and emails to me (as if I'd know!!!!!).

Whether this is a tribute to the diminutive rock god, or a confusion over dates I spoke today to the promoters of the Heaven & Hell tour (Iommi, Butler, Dio & Appice) who were confused as Heaven and Hell will be playing Philadelphia on that night. As they said it was theoreically possible for Ronnie to play Dublin in the afternoon and still fly out for the Philly gig they thought it unlikely.
Now would anyone like to enlighten me as to how this confusion grew up, as my inbox is getting choked with enquiries I cannot answer except as given above!
