Although it might look like a planned piece of entertainment, according to the crowd, the spectacular performance was quite impromptu. (However, it did help that they are professional Irish dancers!)

Conor Flower, one of the Irish dancers and Rob’s nephew, said the performance wasn’t planned.

He told the Belfast Telegraph, “It was all pretty spur of the moment.

“It wasn't rehearsed for weeks or anything – the lads are all cast members of 'Lord Of The Dance' and they just kind of decided to do it."

The bride and groom are both professional dance teachers at The Matthews Academy of Irish Dancing in Coventry in England and former cast members of “Lord Of The Dance.” Both Mairead and Rob toured with the production for eight years and Belfast girl Mairead became one of the principal dancers.
