Singer Sara Bareilles made a young cancer sufferer's dream come true on Sunday (15Dec13) by performing a duet with him during a concert in Orlando, Florida. The Love Song hitmaker was onstage at the House of Blues when she introduced the little boy, named only as Joshua, to the audience and proceeded to sing her hit track Brave with the fan. Bareilles told the crowd, "I want to do something really, really special tonight. There is a very, very special, brand new friend of mine who has come to the show and I want to introduce him to you. "You guys are going to fall in love with him the way that I did. Can we welcome to the stage... Mr. Joshua." Joshua was diagnosed with leukaemia in February (13) and lives by the motto 'Be Brave'.
