DREAM, believe and achieve. These three powerful words were repeated throughout the show by Diversity, the street-dancing, body popping, back flipping stars of Britain's Got Talent, at the BIC.

It was only their second date of a UK-wide arena tour, yet the timing of every move of the eight members of the group and the other performers who joined them onstage, was pure perfection.

Entitled, Limitless: The Reboot, the show had a storyline which saw the Diversity guys each being given a superpower, such as electricity, wind, or the chance to slow down time.

Behind them were bright LCD screens, which would play parts of the story in-between dancing performances and the music ranged from dance, pop and grime to Cliff Richard and Leona Lewis.

Massive kudos to the guys at the BIC and Diversity's backstage team, who worked so hard to make fire shoot out of the stage and fireworks and snow fall from the ceiling.

They also unveiled an incredible amount of trapdoors which were opened to allow the show's character to disappear and re-appear, and allow one of the dancers, Ashley Banjo, to shoot through the air on wires towards the audience.

By far the most popular member of the group appeared to be a small, bouncy, curly-haired lad named Perri Kiely, who is memorable as the youngest member of the group when they appeared on BGT in 2009.

However, his popularity was challenged when a tiny five-year-old with the character name, Theo, came onto the stage, with equally big hair and some impressive moves, including a great and very cute Michael Jackson impression.

It was spell-binding, magical and a showcase of the massive talent that young people can have if they dedicate themselves to something, whether it's dance, gymnastics or simply following their dreams.

Five years after the show, the Diversity boys are filling thousands of seats in the BIC and putting smiles on kid's faces with their positive, boundless energy. If that's not a display highlighting that Britain's got talent, then I don't know what is.
