It looks like they have tap danced their way to more than a quarter of a million pounds.
Sixteen tap dance schools from across the Huddersfield and Calderdale area took part in the annual Roy Castle Tapathon.
And when the sponsorship from the latest event is totted up, it will hopefully see the total raised since it began 20 years ago reach over £250,000.
The money from the tapathon goes to the charitable Roy Castle Lung Foundation, formed in memory of the Scholes-born entertainer, who died in 1994 aged 62 of lung cancer.
Castle was famous for his tapdancing skills and appeared regularly in TV shows and in theatres.
Among those taking part in the tapathon, held at the North Bridge Leisure Centre in Halifax, were the Donna Claire School of Dance, based in Slaithwaite, and the Janet Austin Tappers, based in Huddersfield and Brighouse, along with others from Halifax and Bradford.
Roy Castle’s widow Fiona was among those who went to watch the day-long event at the leisure centre.
The money raised goes towards vital research into cancer.
The first tapathon was put on in 1996 by Derek and Vera Hamer, who danced alongside Roy in the 1940s and 50s.
Janet Austin, who has been in charge of organising the huge event for the last four years, said: “It went really well. The place was buzzing.”
