Katie Hahn's "Lilli" is a marvel -- vocally and otherwise. ​(When I learned from the program that she was returning to her home in the Midwest, I thought, "Fine . . . just leave your voice in Memphis.") Her instrument is perfect for operetta, and it is used to stunning effect on numbers like "So in Love." However, "duck and cover" when the "I Hate Men" number explodes."

The actors, under the rubber-band winding direction of David Ivers, sing terrifically and act even better."

The Guthrie offers us the theatrical version of a summer popcorn movie, as we watch a parade of colorful costumes, athletic dances, and fast-paced action (...).Give a lot of credit to the balance of the cast, who breathe tons of life into the confines of River City."

Katie Hahn as Sally Bowles is fierce and funny, and her final number "Cabaret" is the sad, desperate, determined cry of life that it should be."
