Simon Evans, at 52, is far too young to be a grumpy old man, but he’s doing his best to prepare for the role, with this amusingly dyspeptic standup show at Soho Theatre about the ageing process, and how the evolutionary model appears to be moving backwards. According to his show Genius, things really aren’t getting better, at least in terms of human intellect and those who lead us.

The Glasgow International Comedy Festival kicked off with a performance by one of its most popular performers, Craig Hill, a comic far better known in his native Scotland than south of the border. That may be because his shtick relies so much on knowing the ins and outs of Scottish social classification – anyone from Fife, Paisley or Aberdeen was fair game for insults here, but non-Scots may be none the wiser.

Fern Brady is a young Scot with plenty of provocative opinions – on politics, society and relationships – with a delivery that can only be described as dry as a desert. It means that some pieces of information – as well as a few gags – take some time to pass through the “Is she joking?” filter. 

New Zealand comic Rose Matafeo is a fan of romcoms and has decided she is destined to appear in one at some point in her career. As she explains, it's not possible – as a mixed-race woman – to play the film's heroine, but she is surely a shoo-in for the role described in show's title, Sassy Best Friend; after all, she has the wild hair, the specs and the perky personality that such a character demands.

Hannah Gadsby was awarded best show (jointly with John Robins) at the 2017 Edinburgh Comedy Awards for Nanette, which had already been given the equally prestigious Barry award at last year's Melbourne Comedy Festival.

“I don't want to talk about Donald Trump,” Andrew Maxwell tells us as he comes on stage at the beginning of Showtime, because no matter what comics make up about the US President, he then goes and does something more weirdly comic, more comically weird, than they could ever invent.

Chris Rock, another fine alumnus of the comedy factory known as Saturday Night Live, rarely comes to these shores, so his short arena tour was welcome. He last visited the UK 10 years ago as he had been busy with, among other things, presenting the Oscars, voicing Marty the Zebra in the Madagascar films and bringing up a family.

In the early 1990s, a group of students at Leicester Polytechnic (now De Montfort University) staged an end-of-year comedy project. Three of them – Claire Walker, Abi Palmer and Geoff Rowe – developed the idea into what in 1994 became the first Leicester Comedy Festival; Walker and Palmer have gone on to other great things in the arts and Rowe remained as the festival's director. Under his leadership it has gone from strength to strength – second only to the Edinburgh Fringe in its stature in the industry.

Margaret Cho takes no prisoners: if you don’t like good honest filth or feel uncomfortable around matters of feminism, sex and race, then this Korean-American comic is not for you.

A fair few Edinburgh Fringe shows are just that – things that work perfectly in the “let's do the show right here” spirit that permeates the festival, in a tiny (and often grotty) venue that adds hugely to the vibe. That's all well and good during August, of course, but come later in the year when a show moves beyond the festival confines it can lose much of its spark.
