Among three-year-olds Bella, Fizz, Jake and Milo trip off the tongue as easy as the names John, Paul, George and Ringo do with Beatles fans.
And the Tweenies share some similarities with the Fab Four. Both bands have played big venues (the Tweenies recently starred at the Albert Hall), both have had chart success (five top 20 hits, I kid you not) and both split up over artistic differences.
But while the Beatles never reformed, according to the story of the Tweenies Live, the band split but thankfully, courtesy of a clown called Jangles and a spaceman, they buried the hatchet and reformed. If only Lennon and McCartney had met Jangles (if only Mark Chapman had met Jake).
The Tweenies Live is a rock and roll story for the Huggies generation.
The packed Arena was taken on a 90-minute pop-umentary charting the band's formation in a circus, while the Tweenies were still in nappies, to their current modern day status as the Brotherhood of Man of children's TV characters.
Along the way they managed to murder the hits of Abba, The Blues Brothers and David Bowie's Starman, though I felt they rather improved the cover version of some nameless Steps' hit.
As a spectacle for the toddlers, The Tweenies Live is a winner. Fast-paced, colourful and the emphasis on audience participation means the attention of thousands of ankle-biters is held.
The liberal use of pyrotechnics and regular and garish costume changes also help.
As a personal touch the cuter members of the audience are caught on a camera and their faces beamed out on a huge screen behind the performers.
I've never really followed the TV series but there were some questions that remained unanswered. The relationship between the balding Max and these four cloth kids has always worried me. He's not dad, he's not grandad, yet he's always on the scene. Mum was nowhere to be seen last night.
Doodles the dog did make an appearance though. Now he can talk - or rather, now he can rap. He appeared as the canine king of Bling with his own song, which I fear will chart quite soon.
My four-year-old son certainly seemed to enjoy it. He's growing out of the Tweenies (Teenage Mutant Ninja Turtles and Power Rangers Dino Thunder are his faves) but the show did give him the opportunity to get up and boogie. Boogie in his case being leaping and sliding across the floor and fun fighting with his pal Jack.
There's nothing much for the adults I'm afraid except shelling out cash on popcorn and merchandise.
As Jack's mum left she fell for the oldest trick in the book. Her son spotted Tweenies balloons being handed out by the exit. "Oh look they're giving away balloons," she said as she steered wee Jack towards the floating Doodles.
She found out the hard way that the balloons are free for every £5 handed over to balloon sellers by naive parents. Our Bradley was shielded from the balloons and ushered through the exits. My wallet remained shut and the boy enjoyed his gig. A winning night all round.
