I'm on the mailing list for Iasan & Sebastian Studio Salon (hair salon) and got this email from them:

Hello everyone! We want to invite you again to join us as we sponsor Swing Dance Night atBricktop (1427 O Street). This event now has a permanent place in the weekly line-up and will run every Wednesday, so mark your calendars. A live DJ will spin a collection of big band, classical swing, and rock-a-billy music. Admission is totally free and open to 21+. Open instruction begins at 9pm and open dancing at 10pm. Show off your moves, learn some new ones, and have a ridiculous amount of fun. Bring all your friends. Join us as we jump and jive the night away!

Doesn't that sound like fun??
