Singing along with a film is normally frowned upon at the cinema, but because it's so close to Christmas, we will allow it for today only — and only because the film in question is White Christmas. The 1954 musical features Bing Crosby and Danny Kaye as a pair of dashing veterans who have teamed up as a very successful song-and-dance duo. They meet beautiful sisters Rosemary Clooney and Vera-Ellen and form a quartet, in more ways than one. Together they plan to put on a televised show to save the failing inn owned by our heroes' former commanding officer. Their secret weapon is a treasure trove of great Irving Berlin songs, including "Sisters," "Count Your Blessings Instead of Sheep" and the title track. White Christmas is shown at 2 and 7 p.m. today at the Wildey Theatre (254 North Main Street, Edwardsville, Illinois; www.wildeytheatre.com), and singing along is encouraged. Tickets are $10 to $15 and include a goodie bag of props to use during the screening.
