British composer SIR Andrew Lloyd Webber is determined to cast a black actor in the title role of his hit musical Joseph And The Amazing Technicolor Dreamcoat. Lloyd Webber will attempt to find his next stage star on UK TV reality talent search ANY DREAM WILL DO, and believes altering the currently narrow ethnic scope of the play "would be fabulous". He says, "It's got to be multicultural in every way. I do think - particularly with a rock musical - it would be thrilling if we found a fabulous, gorgeous black JOSEPH. It would be fabulous."
