In our February 26 theater preview, “Entertaining Violence,” we misspelled the last name of playwright Steve Yockey. And in our February 26 music story “Negativland Samples Itself,” we misspelled Jon Leidecker’s name. Also, we incorrectly stated that Richard Lyons is involved in the group’s current live lineup. It’s actually Leidecker. Also in our Insider’s Guide story “Boutique With a View,” we misstated the role of Shantelle Brumfield. She is a colleague, not a business partner.
