ORCHESTRA IN TUNE AT LONGCHAMP Orchestra Stall followed up his success gained three years ago in the Group Three Prix Gladiateur at Longchamp today. John Dunlop`s eight-year-old made it two wins from three attempts this season with a polished one-length victory over Wajina under Thierry Thulliez in the extended 15-furlong contest. After being held up, Orchestra Stall gradually took charge of the situation and he readily held the second. Tajoun, successful in the race last year, was a short head further back in third, a nose in front of Le Tintoret. Orchestra Stall was an 18-10 shot on the Pari-Mutuel.
