I checked the official website of the National Breast Cancer Coalition Fund.
The event is called Les Girls Cabaret (like the name, lol). In myspace it says its a private party... but there is an information on how you can get tickets/be a sponsor from that website. And yup, Marg is indeed scheduled to appear along with PCD, Felicity, Eric, etc... AND I also saw Dana Delany's name in there.
Yeah I wanna see new clips and new photos... CBS isn't giving out anything yet.
There are new spoilers about Catherine in the Season 8 spoiler thread though.
Shane lives in Cali, he loves Marg and Felicity, I really think he should go and watch the breast cancer benefit event. lol.
