Introducing...Mr Keith

It’s Chairsday! Who remembers Mr Benn?
For those who don’t, it was a children’s show about a man who, after drawing inspiration from his immediate environment, would become an entirely different character and enact an adventure for himself and all those watching to enjoy.
Mr Benn was an improvisor.
So we tip whatever novelty hat we are wearing to you Mr B.
Our very own Mr Keith is also a master of assuming other identities (in the legal, improv sense of course). He can appear, as if by magic, in a scene and become whatever the scene needs him to be.
Is Mr Keith the Mr Benn of today?
Happy Chairsday!
