(AllHipHop News) Bow Wow is being taken to court over two missed shows in May and September of 2009. According to a lawsuit filed in Easter District Court of Missouri , Brad Gould/Macsimus Entertainment claims that Bow Wow took $50,000 to appear at a concert in May of 2009 at the Saint Charles Family Arena. The rapper, born Gregory Shad Moss, missed the first date and promised a make-up date, to be held at Rotary Park in September of 2009 to benefit Mothers Against Drunk Driving, Youth in Need, The Rotary Club and other local charitable organizations. According to the lawsuit, Gould, he shelled out another $43,000 promoting the new Back to School Jam, which Bow Wow also skipped. The lawsuit seeks the return of the $50,000 and another $43,000 for fees spent promoting the second date. This Sunday, Hip-Hop mogul Russell Simmons will join supermodel Naiomi Campbell during the 2010 Veuve Clicquot Polo Classic. The event, which attracts a fashionable crowd from around the world, will benefit the American Friends of Sentebale, which is a charity founded by Prince Henry of Wales and Prince Seeiso of Lesotho. Both organizations are committed to assisting orphans in Lesotho, Africa, who are suffering from HIV/AIDS. Guests who can afford to attend the swanky affair will be treated to a champagne lunch featuring spectacular views of the Manhattan skyline, and a thrilling polo match with world-class polo players. Simmons and Campbell serve on the Host Committee, which also includes Michael Alpert, Christine & Renaud Dutreil, Rachel Roy, Amy Sacco, Leslie Stevens, Ivanka Trump and others. The event takes place on Sunday (June 27thth) on Governors Island in New York. Tupac Shakurs classic Hip-Hop track Dear Mama was one of 25 records selected by the Library of Congress to be entered into the National Recording Registry. Shakur joined legends like Little Richard (Tutti Frutti), Willie Nelson (Red Headed Stranger), Bill Cosby (I Started Out As a Child), R.E.M. (Radio Free America), Howlin Wolfe (Smokestack Lightning) The Staple Singers (Soul Folk in Action) and others. In this moving and eloquent homage to both his own mother and all mothers struggling to maintain a family in the face of addiction, poverty and societal indifference, Tupac Shakur unflinchingly forgives his mother who, despite a cocaine habit, never kept a secret, always stayed real, stated Librarian of Congress James H. Billington. The song displays further evidence of hip hop as a musically sophisticated and varied genre that can artfully encompass a wide variety of themes and musical influences.
