When hignfy was pulled last minute, I did that oh-so-modern thing of turning to Twitter to find out why:
"@haveigotnews
Sorry everyone. The BBC have pulled tonight’s edition of #HIGNFY - no, we didn’t book Danny Baker. We booked Heidi Allen, a member of a party no-one knows the name of (not even the people in it), because the Euro elections, which nobody wants, may or may not be happening.
Sorry.

The number of responses to the given reason was shooting up as I read, and to say that viewers weren't happy would be the understatement of the year!
Accusations of bias and incompetence were the main complaints, but fury that Mrs Brown's Boys was deemed a suitable replacement for hignfy wasn't far behind!
