Had the Circa '21 Dinner Playhouse's holiday production Winter Wonderland been staged last year as originally intended, it would have marked a significant anniversary, given that it would have been 20 years since the previous version of this Christmas-themed musical revue debuted on the Rock Island stage. But with the dinner theatre closed for the holidays in 2020, Winter Wonderland, running November 10 through December 29, is now returning to Circa '21 – in altered form – for this year's yuletide season instead. And although a 21st-anniversary presentation may not have the marketing value of a 20th-, staging the revue in 2021 does provide a different number to celebrate.
