Erika Thomas, Susan Granet, Christopher Thomas, and Spencer Clark in The Music ManChristopher Thomas could sell me anything. On Thursday night, he was peddling the character of Harold Hill in a preview performance of Quad City Music Guild's The Music Man, and Thomas plays the part with such bombastic charm - and just a hint of smarm - that despite knowing of the character's swindling intentions, I was buying his Hill's shtick hook, line, and sinker, right along with the good people of River City.

Erika and Christopher Thomas in The Music ManQuad City Music Guild's new production of The Music Man - the Meredith Willson classic running August 5 through 14 - stars husband and wife Christopher and Erika Thomas as romantic leads Harold Hill and Marian Paroo. And just to be clear: Yes, the couple knows how close to nauseatingly adorable it is for them to be playing these roles opposite one another.

"I'm kind of calling this my nursing-home story," says Erika with a laugh. "Like when our grandchildren come to visit, it'll be, 'You know, your grandfather and I were in Music Man once ... !'"

"And they'll be, 'Uh oh ... here comes that Music Man story again ... !'" counters Christopher, also laughing.

"Aida"There seems to be a pretty safe rule of thumb regarding the productions at Quad City Music Guild and the Richmond Hill and Playcrafters Barn theatres: When the actors appear to believe in their material (whether that material is strong or weak), the shows are terrific, and when they don't, they're not.
