Veteran stage producer Michael Cullen, owner of the Mercury Theater, 3745 N. Southport, has been extraordinarily generous with his space over the years, donating it for benefit performances, theater community meetings, and other events. Now Cullen needs other people’s help. In January he suffered a stroke. He’s currently at Schwab Rehabilitation Institute, undergoing extensive therapy to restore his powers of movement and speech, and he’ll need more care when he returns home. Thing is, he’s got neither health nor long-term care insurance, On Monday, April 19, the Royal George Theatre will host a benefit for Cullen featuring an entertainment line-up to be announced. Organizers of the benefit, which begins at 7:30 PM, are suggesting a $50-$75 donation. For more information or to donate directly, go to
