Strictly Come Dancing 2020 duo Janette Manrara, 37, and HRVY, 21, will perform three dances alongside their fellow finalists this evening in a bid to win the Glitterball trophy.Speaking ahead of the live show, the singer admitted he had been in “agony” and was struggling with their Showdance.Speaking to press, including Express.co.uk, about training for the final, he said: “It’s been alright because we have done the Jive and we’ve done the American Smooth [before], so it’s more about going over them again and remembering the steps a little bit and making sure it’s cleaner.“But, the Showdance is an all new dance basically and it’s a lot.“We’ve put everything we can into 90 seconds to the point where we get to certain sections and I have to.
