Updated: 1:55 p.m.There seems to be a bit of a dustup between the Distilled Spirits Council of the United States and the White House but booze has nothing to do with it. According to DISCUS President and CEO Peter Cressy, the Obama administration banned all military bands from playing at the lobby shops annual charity fundraiser at Mount Vernon. In past years, bands from the Marines and the Army have played patriotic songs such as Taps during a fireworks show over the Potomac River. But the bands were absent from Wednesday nights gala. I learned this year that there appears to be an interpretation of a rule now that says you cannot have military personnel participate in a charitable fundraiser, Cressy tells HOH.Army regulations state that bands may play at civilian-sponsored social, civic, and cultural events, so long as they play patriotic music. Army spokesman George Wright says there is a longstanding rule, which has nothing to do with the Obama administration, that forbids Army bands from playing for fundraisers.Its not related to this administration. Its designed to prevent bands from selectively benefitting certain charities, he says.I think its very unfortunate that the band was unable to play, Cressy says. Were certainly going to appeal it.While a military band may not have been present at Mount Vernon, a few Members of Congress and a handful of celebrities did attend the dinner, which raised money for the sites orientation and education center.HOH spied Democratic Reps. John Yarmuth (Ky.) who was inducted into the George Washington Spirits Society and Dennis Kucinich (Ohio). Actresses Teri Polo, Rachel Leigh Cook and Alfre Woodard and actor Steven Webber were also on hand and stayed late into the night.Woodard even went home with a bottle of booze signed by rocker Kid Rock that she won in the galas silent auction.Casting CallLooking to attend President Barack Obamas MTV town hall event next week?
