Terry Alderton is a man with an identity crisis. In fact, he has lots of crises. Is he Terry Alderton the stand-up comedian or Victor Reiths, the bizarre misogynist theatre manager persona which he adopted in the first part of the act? Why did he think that interludes of Dad-dancing would improve the show? Most importantly, is he a mimic who also makes jokes or a comedian who every now and then starts mimicking a motorbike for no particular reason? I really don’t know. Unfortunately for the audience of his comedy show on Friday night, I don’t think he knows either.

At least Alderton manages to get some comic mileage from this identity crisis. His signature gag is to turn away from the audience and vocalize the conflicting voices in his head. When I had got past my unease that these sections were all played very much for point-and-snigger laughs - schizophrenic auditory delusions are of course well known to be laugh-a-minute affairs - there was fun to be found in Alderton’s ability to move seamlessly from the Gollum-like voice of the interior monologue to the range of regional accents which he is able to adopt.

The bulk of the show, however, consisted of uninspired and derivative material. The TV show Loose Women, Australian immigration policy, bus lanes: all potentially fruitful subjects for comedy, but which were raised awkwardly and then suddenly dropped.  “Would you like to come on my Facebook?” – this, the big punch-line to a tediously set up joke, is so old that I believe it is currently doing the rounds of provincial school playgrounds.

Perhaps aware of the weakness of his prepared material, Alderton diverted to audience banter at the slightest provocation. Here, his sheer physical exuberance and accurate mimicry held him in better stead as he bounced about the stage and mimicked the accents of those to whom he spoke, but it was unable to save him. Had he been an elderly uncle doing a fifteen minute stint after Christmas lunch, Alderton’s enthusiasm and the skill of his mimicry alone would have made it enjoyable. Stretched over nearly two hours in front of a paying audience, the show was not a success.
