As the Times Union Center prepares for a major announcement this afternoon — someone or something big is coming this Summer, possibly the biggest act in a decade — early reports out of Kentucky says that it’s Paul McCartney.

McCartney has been announcing tour dates one by one. Among them is a Thursday, June 26, date at the KFC Yum Center.

According to Copiousnotes.com and Louisville.com, Albany and Pittsburgh are among the additional dates.

Bob Belber, general manager of the TU Center, would not confirm McCartney as the mystery act. “I can’t confirm that. . . . I think the local and regional people in this market will be extremely excited, but I still can’t confirm who it is,” he said.
