Taking many of the conventions of old-school stand-up – observational comedy, sound effects, impressions – Alderton gives them a surreal twist before cramming them all together. Some punchlines get lost in the chaos of songs, dancing and vocal mimicry but others loop round returning after 20 minutes for even bigger laughs while some wonderfully twisted internal monologues give a running commentary on this hour of clever nonsense.

Pleasance Courtyard, 556 6550, until 28 Aug, 9.20pm, £10.50–£12 (£9–£10.50).
