The BBC’s over-the-top promotion of a new “Joseph and the Amazing Technicolour Dreamcoat” at the Adelphi is another example of how little the Beeb cares about theatre, writes Michael Billington. “Would the first night of a new play by Stoppard, Pinter, Ayckbourn or Hare get the same attention as Joseph? Of course not. With very rare exceptions on BBC4, the corporation doesn’t even bother to televise the key works of modern drama. As for the classics, forget it. You have as much chance of seeing a play by Shakespeare, Ibsen or Chekhov on BBC TV as of a cow jumping over the moon.”
