Rather like housebuying, in theatre location can be everything. Tom W Lister’s tragic comedy about the breakdown of a young genius of a university lecturer would be a good play no matter where it was performed - but setting it in an Edinburgh University lecture hall and then performing it in an Edinburgh University building is a lovely twist.

Daniel Pirrie gives a pitch perfect performance as the tortured genius Allen whose world is turned upside down when the woman he loves gives him Sting concert tickets for his birthday. Allen (quite rightly) despises the sanctimonious pop star and begins to question his relationship.

The only way for him to try to accommodate her liking Sting is to abandon the Cartesian thesis he has been awake for five days and nights working on and turn it into a practical experiment - can he convince Sting to remake all of Nick Nolte’s movies (in the Nolte role) because then and only then will Allen be able to appreciate his ‘talent’ enough to see him in concert.

A funny concept, but with a dark core. Pirrie could not be better or bettered in the role. His adlibbing with the audience while in character is superb. He finds his character’s arrogance (and, ironically, santimonious nature) but does not let it overwhelm his vulnerabililty.

He has a great chemistry with Kati Markkanen who plays his long suffering girlfriend Bessie. This is a real must see.
