This infectiously upbeat musical is the most fun you’ll have in a long time. Following the music of Thomas “Fats” Waller, the five vocalists segue from one number to the next. You’ll recognize popular tunes like “The Joint Is Jumpin’,” “Honeysuckle Rose” and “Black and Blue” and laugh at others like “Your Feet’s Too Big” and “Fat and Greasy.”

The cast looks like they’re having so much fun, teasing, flirting and poking each other, the joyous mood onstage is contagious. It’s hard not to smile, tap your toes and sway to the rhythms. From the first song Fats ever recorded (“’T Ain’t Nobody’s Biz-ness If I Do”) to the title song, the music of Fats and this soulful and celebratory production, is a feast for all of the senses.

The Ahmanson Theatre is located at 135 N. Grand Ave., Downtown. For more information, visit
