Admit it. If you hear the right Madonna song, all your cool goes out of the window and the dancing shoes come out of the closet. This week you have two chances to take all that enthusiasm and latent star power out of the house and learn some Madonna choreography with other folks.

Tomorrow on the 20th at the Bollywood Cafe and again on Saturday the 25th at the Dance Mission Theater, you’ll have two chances to learn all the moves (‘tude not included) from Madonna’s 1989 hit “Express Yourself.” In October, there will be a huge, public flash mob performance that will include other choreographed Madonna hits like “Vogue” and “Holiday.”

Classes are free and open to the public, but donations are welcome and will be happily accepted. Check out the site for more details.
