The Bushnell in Hartford is filled with familiar tunes from movies and musicals delivered at the hands of the Boston Pops Esplanade Orchestra.  It seems like the performers enjoy the evening us much as the audience.  We even get to sing along.  There is a feeling that the performance is not quite complete when they close without playing Stars and Stripes.  Not so fast, there is an encore…Stars and Stripes; giant unfurling American flag and all.
