Welsh comedian and ‘fully fledged light entertainment personality’ Rob Brydon is currently starring in Future Conditional, the first production at the Old Vic theatre under its new artistic director Matthew Warchus, who has taken over from Hollywood actor Kevin Spacey. The play tackles the challenges of the British schooling system – a subject  I have a close working knowledge of- written by Royal Court director-turned-writer Tamsin Oglesby. Rob plays an English Teacher, God held him.  And it was the good Lord who was uttered as he saw this sketch when I stopped him whizzing out of the Old Vic stage door on Saturday night. I think it was an exclamation of admiration rather than a call to the almighty for help. “Oh my Lord,” he gasped followed by “Yes,yes.yes.”- the holy trinity of confirmation to my signing request.
