"Leading the musical comedy at Riverside is Sandy Bainum and she is the picture of glamor, grace, charm and offers a vivacious portrayal of everyone's favorite aunt. Bainum has the elegance, beauty and winning vocal power to enchant the full houses that seem to be the fate of this production. The comic turns are in good hands with Bainum but she handles the music like a Broadway star. Whether she is warbling "Open a New Window" to her new-found nephew or delivering her 11 o'clock number "If He Walked into My Life," Bainum makes Mame's songs her own."
