SAY HELLO TO . . . DICK TODD—the baritone soloist in Home Town, Unincorporated. Dick comes from Montreal, and was already established as a popular singer in Canada before he headed south of the border, down U.S.A way. In this country a couple of guest appearances on the Magic Key of RCA show, and a season as soloist with Larry Clinton’s orchestra, brought him a large and lusty fan following. In physical makeup, Dick’s built like a football player: no wonder, because he was one, in McGill University. Boxing, swimming and wrestling are a few more things he was noted for in college , where he studied engineering.
