Glassed

Last night's imagine... on BBC1 ended with Ptolemy Dean, who looks after the fabric of Westminster Abbey, joshing with his sister, Tacita, and Dr John Hall, the rather smug Dean. Says Ptolemy, "No other cathedral could have got away with it".

The previous hour and two minutes featured the commissioning of a stained glass window from David Hockney, tapped up by Tacita (also Los Angeles-based) on behalf of Westminster. Alan Yentob spend some time with David at the opening ceremony, but it was essential that he visited the Hockney house in the Hollywood Hills to build up the dramatic tension. There was a script editor in the credits, but was anything left unsaid, as the lead was extruded around the coloured glass ?

Last year, the Abbey's income was £35.3m, from visitor fees, donations and investment income. Financial reserves stand at £22.6m. 'Charitable' expenditure was £26.5m - will the Hockney fee be classed as such ?
