The business consultant first saw Rock of Ages in 2009 after learning one of his favorite actresses, Amy Spanger, was in it. She wasn't in the cast that night, July, 1, 2009, but he fell in love anyway.

"It's the way they took the songs and shaped the story and conveyed the emotion," he told the New York Post. "That's different from anything else I'd seen before."
"People hear a number and think, 'You're nuts! You can buy a car for that!' " he added. "People have seen Bon Jovi concerts a hundred times -- it's what they enjoy. This is what I enjoy."
He said he doesn't think the actors consider him a stalker for how many times he's attended. In fact, the producers gave him a ticket to his 500th show on the house.
"Seeing a familiar face in the audience gives [them] a little bit of a boost," Calimag said. "They know someone was there who cared enough to see them."
