Lewis Schaffer is Free Until Famous, £10

Brooklyn-born honorary Brit Lewis Schaffer (he's lived in the UK for years now) might not yet be famous, but he's still decided to start charging for his solo show, 'Free Until Famous'. We like to think of Schaffer as a professional underachiever – his gigs can sometimes be more like a strange group therapy session than a 'show', and they're often exhilarating. Dry, ultra-loose stand-up.
