A surprise visit by former Britain’s Got Talent runners-up Twist and Pulse meant visitors to St Katharine Docks were dancing in the street on Friday.

The fast-moving twosome, who came close to claiming glory on the ITV show last year with their street dancing and robotic moves, led a “flash-mob” party by the docks and guided dancers through their routine.

They had already made instructions of how to do their dance available on YouTube and fans eagerly arrived to show off the new steps.

The event was organised to raise money for young person’s charity Fairbridge which works to tackle youth unemployment and crime.
