The Moore-Hannon combination struck again as Bonnie Charlie won The Construction Index Conditions Stakes.
Galeota claimed the Construction News Scarbrough Stakes for the second year in a row on the opening day of the St Leger festival at Doncaster.
With Ryan Moore on board, the Richard Hannon-trained six-year-old took his fourth victory in Doncaster with a win by three quarters of a length.
Ballantrae kicked off proceedings with victory in the Flakt Woods Nursery.
Meanwhile, Slugger O'Toole eased to victory in the Heating And Ventilation News Handicap, while Judge 'n Jury claimed the Emap Glenigan Sprint Handicap.
Perks, ridden by Jimmy Quinn, made short work of his two rivals in the Hire From Hewden Conditions Stakes.
John Dunlop's runner cruised to victory by three lengths in an impressive ride by the Benny Andersson-owned horse.
Quinn said: "He won here on soft ground early in the season and he is different class on this sort of surface.
"He had a couple of bad races on ground that didn't suit, but he quickens on that like it is good ground."
But it was the success of Hannon and Moore that was the real highlight of the first day at Doncaster.
Hannon's assistant Richard junior said of Galeota: "He has had his problems and still has, but we still get him to the track. He loves it here and he still enjoys it too.
"He is in the Portland on Saturday but it would be a big ask to run again under a penalty, and he is four from four here so I wouldn't want to ruin his record.
"There is a race for him at Newmarket on Champions Day and there is also the Diadem, although I am not sure that Ascot suits him."
And racing manager James Stafford said Bonnie Charlie could go on to bigger and better things.
"He disappointed us a little at Newmarket last time but the ground was faster than he wanted, and I do think give in the ground is key to him," he said.
"He will stay in training next year and we would love to win a Listed race with him.
"We won the Scurry Stakes at Sandown this year with Corrybrough and that could be the race for him."
