He limped on to the stage, foot in a plastic cast, leaning on a crutch. He looking tired, dishevelled even, and quickly started burning up under the stage lights.

But talented pianist Adam Kay transformed when his fingers danced along the keys and his smutty songwriting rang around the sold-out Dukebox Theatre.

The wonderfully rude and hilariously funny adaptations of old favourites, from 80s pop hits to Christmas tunes, had everyone in hysterics. Even Kay himself struggled to smuggle a smile at points.

He was “put into” Brighton Science Festival because of his former career as an anaesthetist. He left the medicine behind to pursue a career in comedy – thank goodness.

Under Kay’s talent Lady Gaga’s Poker Face became an informative tune about ensuring the spoon is taken out after making tea, Noel becomes a tale about a missing letter on a computer keyboard and Close To You is a story about a colostomy bag. Of course.

His Going Underground adaption to vent frustrations at Tube strikes was an internet hit several years back – and its appeal has failed to wane.

His songwriting was akin to Tim Key’s talents with poetry. Kay is a thoroughly enjoyable genius.
