The dream lives on with Gailileo for the Derby,' concluded the Ballydoyle maestro, who last completed the Irish Guineas double in 1997, via Classic Park and Desert King.Seamus Heffernan (28) whose only other Classic success came in India, remarked, ' It's great to ride my first Irish Classic win and this filly will certainly get further.'Fantastic Light continued his rich pickings around the world when he landed the IR#200,000 Group 1 Tattersalls Gold Cup under Frankie Dettori at the Curragh on Sunday afternoon.Winner of the Man O'War Stakes at Belmont Park in America and the Hong Kong Cup last season, the five-year-old was sent off a warm 5/4 fav. with Breeders Cup Turf hero Kalanisi next best on 7/4. But it was the 7/1 British raider Golden Snake that threw down the biggest challenge in the concluding stages with Pat Eddery's mount only going down by a neck to the Godolphin market leader. Kalanisi finished a never threatening 3l back in third while best of the domestic challenge was Bach (5th) with Muakaad last of the six.After Dettori performed his customary Group 1 flying dismount in the winners enclosure, Simon Crisford, Racing manager to Godolphin, said: 'He's very special and a fantastic horse. He'll probably go for the Prince Of Wales next while the King George is his main summer target. He'll have a big campaign in Europe and is entered in all the big races ranging from 1 John Murtagh continued his recent rich vein of form when he conjured up a renewed effort on Pugin (5/1-6/1-5/1) to defeat March King in the Silver Stakes.Aidan O'Brien nominated the Chesham Stakes at Royal Ascot for his juvenile colt Monarchoftheglen after the son of A P Indy quickened up at the distance to forge ahead for a narrow victory over gallant market rival Rum Charger.'He's a beautiful horse and Mick (Kinane) educated him as he had to get himself out of a bit of trouble out there. Mick also said he wants much better ground,' said O'Brien. Dermot Weld's top-weight Caumshinaun (9/2-7/2f) and Pat Smullen justified good support to run out the 1L victor of the 6f handicap while Irish Empire and Eddie Ahern scored by a similar margin in the 27 runner 1m handicap for Michael Grassick..
