RENAISSANCE man is a title that sits very comfortably on Alexander Armstrong's shoulders. Nothing seems to be beyond his capabilities, with the performing enjoying successful careers in acting, singing and presenting.

But now, in news that will delight his legions of fans up and down the country, he is returning to his first love – live comedy.

Armstrong will be coming to a Darlington Hippodrome with his new stand-up show "All Mouth and Some Trousers."

The comedian is talking to me in the run-up to the tour, which opens at the Warwick Arts Centre on November 3. He is a rare mixture of the comic, the charming, the captivating and the charismatic.

The performer, who has a huge following from Pointless, his exceedingly successful BBC1 daily quiz show, is really looking forward to reviving his overriding passion for stand-up. "It's been a long time since I've performed comedy, as all sorts of other things have sprung up since we stopped doing Armstrong & Miller in 2010," he says. "Pointless being the big one.

"But live comedy is where my roots lie. It is where I come from, and it's still my great love. I'm so excited to be coming back to it."

Armstrong, who, since they met in the early 1990s, has had an enormously fruitful double act with his close friend and fellow comedian Ben Miller, says he is thrilled to be returning to the sheer buzz of live comedy.

He relishes the spontaneity of stand-up and the fact that every single night on the road is different. "I guess you’ve laid the tracks that your train of thought might run on, but you’ve got, well, different passengers on board every night," he says.

“Each show is a totally different experience, which depends entirely on the audience. As long as you're not glued to a script, on any night you will go along with what that particular audience is enjoying. I love that about stand-up.”

Armstrong, 49, who in his early career was a much in-demand voice-over artist, has also provided voices for many children’s animations including Danger Mouse, Peppa Pig and Hey Duggee. When asked to explain the title of his live show – "All Mouth and Some Trousers" – he laughs, saying perhaps it refers to his desire, after a long period in other fields, to pull on his “comedy trousers” once again. "I felt, on balance, that the mouth had had all the running for a bit. Time to give the trousers a pop. If you see what I mean…

“I absolutely adore doing Pointless, but my job on that programme is to keep the boat steady and to play it off a fairly straight bat. The live show is just a lovely chance for me to have a free hand. It's all very light-hearted. It's just about me returning to my first love: writing stuff and creating characters that make me laugh.”

The performer, whose versatility is underlined by the fact that he has also released three bestselling albums, A Year of Songs, Upon a Different Shore and In a Winter Light, emphasises that "All Mouth and Some Trousers" will be a show with broad appeal. "There will be something for everybody. Anyone who's enjoyed watching me on Have I Got News For You or who was a fan of Armstrong and Miller will definitely enjoy this. There's plenty there for everyone. Everyone is welcome.‎"

He adds: “Perhaps it is not for the Hey Duggee crowd, yes I think it might be a bit much for them but definitely for their parents. And if they enjoy it they can tell the kids about it in the morning.”

The show centres on Armstrong's early days in showbiz, and the strange business of trying to find a career in whatever door of the industry he could get his foot into. The performer, an actor who has starred in Beast, Life Begins, Doctor Who, Mutual Friends, Hunderby and The Sound of Music Live, focuses particularly on his time as a voice-over artist.

Armstrong, who also presents a widely loved show on Classic FM every Saturday and Sunday, recalls: "I would spend my days in a succession of dark, sound-proofed rooms, listening to myself yelling 'the sale must end Sunday’ again and again.

"Meanwhile, in another room there would be a panel of 15 seemingly sane adults who would stop me every five or six takes, go into a huddle, come out and saying, 'Can we listen to take 74 again? We felt that one had more warmth'."

He continues: "Hours of my life would spool by in that weird soundproofed bubble. And I adored it! As the voice-over, you’re pretty much the last piece in the jigsaw. They’ve done everything else: the ad’s all shot and edited, the picture’s been graded, the sound effects have been put on, but up until you arrive they’ve had to work to some rough guide vocal done by a producer, so everyone gets genuinely excited about getting this last bit done.”

Unsurprisingly, all this makes for excellent comic material. "It's certainly a window into a ‘different’ world," smiles Armstrong. "And of course, it's peopled by total lunatics, but some genuine originals. And some bonkers stories.

"It was my only job before Armstrong and Miller took off in the mid-2000s. For 15 years, I was in the thick of it, earning my crust doing voice-overs – and it could be a decent, ‘cheese-filled’ crust at times.”

Armstrong, an infectiously positive presence, underscores what he hopes audiences will take away from "All Mouth and Some Trousers". "If I have a central philosophy – and it does come into the show – it's 'For God's sake, be happy'. Don't settle for anything less than you deserve, but let’s stop making ourselves miserable. People have started working themselves into such a stew about things that simply don’t matter.”
