Mason is offering her new show, which is entitled Setting New Standards, through Feb. 14. She is accompanied by pianist Christopher Denny; Barry Kleinbort directs.

In a mass e-mail, Mason said, "Christopher Denny and I are doing six shows with new music (songs by Barry Kleinbort, Paul Rolnick, among others), new arrangements (well, of course!), and most definitely for all my friends in Chicago, I will be performing my song in Wonderland: 'Off Wit Their Heads!'"
