Unusual casting call: Hip Hop Group needed for wedding, with potential for good publicity

For serious dance crews looking for some publicity or exposure: this just hit my mailbox: 
"We are very interesting in booking one of the top hip hop dance troupes for a spectacular performance at the historic Andrew Mellon on Constitution Avenue in Washington, DC for Saturday June 12th.  The troupe of between 9 to 15 dancers will be performing  at approx. 10 pm that evening for the finale of a major wedding reception with 550 guests at a sit-down black-tie dinner.  All guests will be the elite of Washington, DC and the event will be covered by The Washington Post newspaper and the Washingtonian magazine.  We will appreciate hearing from you really quickly!  Please email  Michele Granger at verachawla@gmail.com or call 301-928-1484."
