Although billed as a musical centred around Brexit, Leave to Remain is decidedly a love story. The Lyric Hammersmith boasts this new musical written by Matt Jones and Kele Okereke, which runs till February 16. The two writers contribute their unique and individual perspectives to this rich story centred around Obi (Tyrone Huntley), born to west African parents, and Alex (Billy Cullum) an American ex-pat.
