Being adopted at birth might not sound like the easiest subject matter for a stand-up debut but Canadian comic Bobby Mair is able to walk any potential line of icky sentiment and crude offence with a winningly vulnerable stage demeanour. Ultimately, there is none of the former and plenty of the latter as he lets his crowd work out just where their taste-default marker is. Will it be crossed by the bit about waking up to find you’re being urinated on by a relative stranger? Or maybe it’s the moment he confesses the real reason he’s anti-abortion?

Clearly, Mair is not waiting around for that call where he is asked onto Michael McIntyre’s new chat show, but he should be getting set for more acclaim if he can nail the looser parts of his act while maintaining the ragged edges that make him such a fascinating young comic.

As he told us last year ahead of his full Edinburgh Fringe debut, ‘I would say that I’m on the dark side, but I don’t think I’m as dark as some other comedians. I just love jokes and I don’t know where my point of view comes from. I don’t class myself as a dark comedian, I’m sure other people might, but to me it’s just the normal thing. In one joke I take revenge on a woman who I bumped into and she got angry; so in my fantasy I toss myself in front of a train, and die and then dump my tombstone on her front lawn.’ Yep, that’s pretty dark.
