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.
