Jimmy Rabbitte hates jazz, always has. But his wife Aiofe loves it, and Jimmy loves Aiofe. So when, in attempt to convert him, she buys him two tickets for a Keith Jarrett concert he decides to take Outspan, former member of Jimmy’s band The Commitments, who has come back into his life after a chance meeting in the cancer clinic. Jarrett is famous for being intolerant of any noise at all – a cough, a sneeze, a wheeze – from the audience, stopping playing and shaming the perpetrator. And Outspan’s diagnosis is lung cancer, it’s pretty bad, and he needs an oxygen cylinder to breathe properly.

Will Outspan create havoc? Will Jimmy learn to love jazz at last?
