THEY have been riding the crest of the wave for almost 20 years with 'Riverdance'.
And as they excitedly begin work on their latest production, even John McColgan and Moya Doherty admit they never know whether a show is going to be a hit or a miss.
The husband-and-wife duo were casting an expert eye over the moves of dancers from all over the world, who congregated in Dublin yesterday to audition for the show which opens at the Bord Gais Energy Theatre on September 25.
Amongst them was Aoife Kennedy (22), a physiotherapy student from Trinity College – the only Irish dancer to make the line-up.
The young woman from near Skryne, Co Meath, hopes to combine her studies with dance, spotting a niche in dance physiotherapy.
Meanwhile, Irish dancer Ceili Moore (18), from Sydney, Australia, said she was amazed to get 7,000 votes in the online voting and that it would be a dream come true.
Both Moya and John spoke of 'Riverdance' as an epic success story that they had not seen coming.
"I knew we had something special – I certainly never thought we'd get 20 years," said John.
