More Joyous, the horse at the centre of the simmering feud between owner John Singleton and trainer Gai Waterhouse, has been retired. The champion mare won eight Grp One races, a record only bettered by Black Caviar and Sunline for a mare in the modern era. Her last race was hit by controversy and sparked a much-publicised stewards inquiry after Singleton claimed Waterhouse passed on inside information about the horse.
