Promising humour so intelligent that 'Einstein wouldn't get it', the Sheeps trio of Liam William, Daran Johnson and Alastair Roberts might not reach quite those relatively stupendous heights, but audiences should be prepared for a frequently hilarious hour. Live And Loud Selfie Sex Harry Potter opens up as the threesome arrive in top hats and canes for a deliriously over-the-top opening number, crooning with gruff, larynx-scorching voices about how this show will be 'good'.

Thereafter follows a series of routines which easily ramp up that modest claim while a narrative continuum is provided by Johnson's off-stage relationship breakdown and his colleagues' utter indifference to his misery. Meanwhile, the actual reason for their Edinburgh reunion (they last appeared at the Fringe in 2014) is finally revealed.

Among the many highlights are a multi-layered sketch that keeps going wrong and two British diners experiencing curious extras to a bill at a Dutch restaurant, while alt-right academic Jordan Peterson makes an appearance and a thriving tech company has to deal with its odd third wheel. Asides from one slightly clumsy semi-satirical piece about Syria and their deliberately bad musical sequences, there's barely a false note to be found in this heralded comeback.

Pleasance Courtyard, until 27 Aug (not 25), 7pm, £10–£14 (£8–£12).
