British horse racing was plunged into mourning when promising jump jockey Campbell Gillies, 21, drowned on holiday in Corfu last June.

The Scot, of Haddington, East Lothian, had captured his first Cheltenham win on Brindisi Breeze in the Albert Bartlett Novices' Hurdle, and was tipped as a rising star.

Now Irish singer Mark Boylan, whose horse racing-inspired songs have become a hit on the internet, has written a musical tribute to Gillies which will be played as riders parade on Friday.

The jockey's sister Lesley said: "Campbell's friend, [fellow jockey] Zander Voy, said he used to drive him mad playing his songs in the car. They would be on repeat going to the races.

"Campbell was a full-on person. If he liked something, he liked it constantly. I have mixed feelings about Friday. It will be an emotional day but we will try our very best to celebrate Campbell's life."

Mr Boylan, who is a teenager from County Offaly, said: "It was a terrible, terrible thing that happened and I guess my job was to capture him as best I could. The last thing I wanted was a morbid song."
