Say 'I do' to the triumphant return of Edinburgh Comedy Award nominees Max & Ivan. (BBC Two's W1A, Radio 4's Casebook...) Commitment is the true story of the unreasonable lengths one best man (Max) will go to give one groom (Ivan) the greatest weekend of his life. It's a show about dreaming big, growing up, and trying – but ultimately very much failing – to make it in the band. Directed by Kieran Hodgson. 'Astonishing' ***** (Times). 'Joyous' **** (Independent). 'Phenomenal' ***** (Mirror). 'First-rate' **** (Scotsman). 'The real deal' **** (Guardian). 'Essential' **** (Telegraph).
