Robbie Waterhouse points finger at John Singleton in More Joyous saga Robbie Waterhouse leaves the Ivy bar in Sydney yesterday after his annual autumn lunch. BOOKIE Robbie Waterhouse inflamed Sydney racing's best stoush yesterday by claiming John Singleton had started their ugly verbal battle over the More Joyous saga. Waterhouse and Mr Singleton locked horns at Royal Randwick late on Saturday when Mr Singleton sacked Waterhouse's wife, Gai, as his trainer, and accused the couple's son, bookmaker Tom, of telling friends More Joyous could not win. More Joyous blew from $2.50 to $3 with bookies before her run in the All Aged Stakes on Saturday. But the Waterhouses looked like they didn't have a care in the world yesterday as Robbie hosted his annual autumn lunch for close friends and clients, including Black Caviar owner Neil Werrett. The Daily Telegraph was invited to the lavish lunch at Ivy in the city, and while Robbie Waterhouse remained tightlipped about next Monday's stewards inquiry, he wanted to set the record straight about his run-in with Mr Singleton. "He said something to me rather me saying something to him," Waterhouse said. The Daily Telegraph understands Waterhouse was told by Singleton to "go f--- yourself." "I walked down to the alleyway in the bowels of the stewards room and John was there on his own," Waterhouse said. He made a few comments to me. But I'll leave it for the stewards. Gai Waterhouse refused to comment on Mr Singleton and their public falling out after 35 years of friendship. "You can ask me about anything except that," she said yesterday. Yesterday, Racing NSW stewards continued to sift through evidence of More Joyous' seventh placing in the All Aged Stakes at Royal Randwick and the Waterhouse-Singleton clash that followed.

Picture: Rohan Kelly Source: The Daily Telegraph An inquiry was set for Friday but chief steward Ray Murrihy rescheduled it for Monday next week. He said it had been difficult to ensure all the parties could attend on Friday, adding that some stewards would be in Wagga Wagga for that club's Gold Cup Carnival. Murrihy said the verbal blow-up between Robbie Waterhouse and Mr Singleton after Saturday's stewards inquiry had been adjourned would be addressed. "There was an altercation between the two and that will be part of the inquiry," he said. There will be questions asked about what was said. There is so much anticipation about the Waterhouse-Singleton row at Racing NSW's Druitt St headquarters reporters need to RSVP to attend the hearing. The public will be locked out. Mr Singleton, former ad guru and radio magnate, is Sydney racing's biggest name. But he risks being charged under the Australian Rules of Racing with bringing racing into disrepute should he not be able to substantiate - or withdraw - his Waterhouse claims.Murrihy said he had not received a request from any of the parties to have any of the hearing heard in camera. Under racing's rules, the Waterhouses and Mr Singleton will not be able to sue for defamation for any comments made during the inquiry. Confirmed starters for the inquiry include Robbie, Gai and Tom Waterhouse, Singleton, his racing manager Duncan Grimley, Gai Waterhouse's vet Leanne Begg, Mr Singleton's vet John Peatfield, trackwork rider Steve O'Halloran and jockey Nash Rawiller. Sky Racing's Andrew Bensley on the falling out between More Joyous owner John Singleton and trainer Gai Waterhouse. Rawiller, who also attended yesterday's lunch, gave stewards at the original hearing his thoughts on More Joyous' run on Saturday. "When she got balanced in the race, she gave me a kick of about 30m when she usually gives me a kick for 300m," he said. Yesterday he said More Joyous "just wasn't herself." Murrihy also said his panel would look at the comments made by former rugby league player Andrew Johns on Channel 9's Sunday Footy Show. Johns said he had backed More Joyous, but said "the horse was off." He later said Tom Waterhouse had never mentioned "the health of the horse." "We will look at that (interview) along with all the interviews and decide whether those matters need to be acted on," Murrihy said. The racing world has been abuzz since Mr Singleton's sen blow-up on Saturday. He claimed Tom Waterhouse had told his "close mates" More Joyous couldn't win. Mr Singleton and Gai Waterhouse clashed in the Randwick mounting yard before the race, and when More Joyous drifted in betting and finished seventh, the pair argued again. They were called before stewards to sort out their differences. It was during the inquiry that Gai Waterhouse said More Joyous had heat in her neck after a Thursday morning track gallop, and her blood readings weren't 100 per cent. But she said her son Tom had said nothing about More Joyous to anybody. Last night Gai Waterhouse flew to Warrnambool, in Victoria, for this week's jumps festival. Her first jumper, The Nemesis, has been scratched from the festival because of soreness. Asked if she would still enjoy herself given the More Joyous drama hanging over her head, Waterhouse said: "Of course I will. Why wouldn't I?.
