US R&B singer Usher has promised to roller-skate during his Super Bowl half-time show, in Las Vegas, on Sunday.

He said would recreate a skating sequence that had become a viral highlight of his recent Vegas residency, while the show would be a “crescendo” marking a “new beginning” in his 30-year career.

Previous Super Bowl half-time show performers include Katy Perry, Prince and Beyoncé.

But Usher will be the first independent artist to take the stage, having left his previous record label, RCA, to self-release his album, Coming Home, this weekend.
