Following the Thursday evening performance of Spamalot, members of the cast will head to Oz (800 Bourbon St.) for a cabaret performance to benefit the Beacon of Hope Foundation. Admission is free but attendees are encouraged to make a donation. Performers include Caroline Bowman (Lady of the Lake), Steve McCoy (King Arthur), Marty Glyer (Sir Robin), Jacob Smith (Sir Galahad) and others. There will be silent auctions for Spamalot memorabilia. The cabaret begins at 11 p.m. Beacon of Hope has helped neighborhoods organize and rebuild following Hurricane Katrina and the levee failures.
