PRINCELY PURCHASE: Formula 1 race car driver Lewis Hamilton has ponied up $100,000 to buy the custom gold-leaf Fender Stratocaster guitar that Prince has been playing on tour. Proceeds will go to children's and community-based organizations. Hamilton and his girlfriend, actress and Pussycat Dolls singer Nicole Scherzinger, had joined Prince onstage at a concert in Abu Dhabi following the 2010 Grand Prix. Prince had ordered the guitar from Fender's Custom Shop in Corona, Calif., to be a unique component of his "Welcome 2 America Live" tour when it began late last year in New York. The guitar is gold-plated from head to toe, although it is not solid gold, as has sometimes been reported.

ON A SOUR NOTE: The Philadelphia Orchestra, which made mushrooms and hippos dance in Walt Disney's animated "Fantasia," has filed for bankruptcy protection.

Remaining performances this season will go on as scheduled.
