Self-proclaimed 'Sneaky Irish Dance Crew' the Sneaky Steppers are among those who have accepted Ellen DeGeneres' St Patrick's Day 'dance dare'.

The TV host asked people to do a sneaky Irish jig behind unsuspecting members of the public, with the Sneaky Steppers taking to the streets of London for the dare.

On their YouTube channel, they said: "When Hammerstep [Sneaky Steppers' parent troupe] found out a few days ago that Ellen was having a sneaky Irish dance dare on her show, we thought it was a perfect time to put our public dance ambush crew Sneaky Steppers into action for St Patrick's Day!"
