Colourful Irish trainer Oliver Brady died peacefully in his sleep on Monday evening following a long battle with cancer, confirmed Horse Racing Ireland.
The County Monaghan trainer was well known for his celebrations in the winner's enclosure, when he would usually make a rousing speech and lead an impromptu sing-song.
He was first diagnosed with cancer in 1995 and underwent several operations since then.
Brady was given just six months to live in 2003 after a cyst the size of a golf ball was found in his stomach.
In 2008 he had a quadruple bypass operation to unclog arteries that were up to 97 per cent blocked. He was also a diabetic and has problems with his lungs.
Yet despite all of his health problems, Brady tirelessly devoted his life to his horses and to raising money for the Shabra Charity Foundation which he established with his business partner, Rita Shah.
Brady's first winner was Barr's Hill at Navan in 1985. Among his best horses were Maralan, who won two Grade Two chases within the space of a week in February 2008, and Ebadiyan, successful in the Grade Three Punchestown Juvenile Hurdle in January 2009.
Both horses were ridden by John Cullen, who described Brady as a "great man".
He said: "I've only just been told and it's very sad.
"He was a great man and a great trainer of a horse. I can't really think straight, to be honest.
"No one has a bad word to say about him.
"He did lots of work for charity and even when he was very sick the charity was the first thing on his mind."
