The idea is as simple as it is bonkers, but with perhaps a nod to the old BBC Two series Stella Street. Tina Turner has retired from showbusiness and is now a tea lady, making ‘simply the best’ cuppa in town.

So here the diva in a tabard delivers a feisty concert of her greatest hits, but with lyrics changed to reflect her new career. Lady sings the brews.

Such parodies can be the lowest form of wit, but Tracey Collins, the woman behind the caricature, has elevated this into something special by seeking the laughs from Turner’s bolder-than-brass personality, not a few puns set to music. She knows it is the singer, not the song, that’s important.

She belts out the numbers with the familiar throaty rasp; owning the stage and the audience. She flirts aggressively with them all, ordering her prey to touch her leg, or more. ‘I’m naaaasty,’ she growls, gutturally. Few can resist such bestial power, and the force of her personality gets the crowd involved in some hilariously spirited shenanigans, not quite Adam Riches in a fright wig, but on her way.

The drawback is what you probably expect; drawing this fun but essentially one-joke character out for 45 minutes. Collins does pretty well, with a varied mix of songs, banter and set-pieces. Yet some segments, such as reading extracts from her showbiz diary, seem like filler, as she invents anecdotes about encounters with other soul legends. Yet even here there are some nifty gags along the way.

Feeling competitive about Cher’s ongoing success leads to a conga through her venue – it made some sort of logical sense at the time – notching up another high from this anarchic and spirited performer. But perhaps Ms Turner is best showcased alongside other performers and creations, so the madness can be concentrated.
