The Howard County Historical Society has scheduled several new programs in its Music at the Museum series. These are held at the Museum on Court Avenue, in the old Presbyterian Church building. By the way, they have done some remodeling in the old building and now have a handy modern bathroom facility available for visitors. Coming up on Saturday, Nov. 8, is a retro-concert featuring "Rearview Mirror," at 7 p.m. The duo, Iris Hirsch and Glenn Bullion, will be offering selections from the Everly Brothers, the Drifters, Elvis and the Shirelles. They like to involve the audience and make sure everyone has a good time.
