Broadway legend Donna McKechnie, the original Cassie in A Chorus Line, has talked and sung about her life in San Francisco. In 2001, she brought Inside the Music to the Alcazar Theatre. The Tony Award-winner is back in town, still chatting and warbling about her storied life, but this time in a much smaller (and shorter) show in a much more charming room (Feinstein's at the Nikko).
