Chanteur was a brown horse with a broad white blaze bred by Francois Dupre at the Haras d'Ouillystud farm in Pont-d'Ouilly, Calvados. He was the most notable horse sired by Chateau Bouscaut, a French stallion whose wins included the Prix du Jockey Club in 1930 and the Prix du Cadran a year later. Chanteur's dam La Diva was a half-sister to the Grand Criterium winner Pantalon. La Diva later produced La Divine, the dam of Tanerko, a colt who won two runnings of the Grand Prix de Saint-Cloud and sired the Derby winner Relko. Chanteur was trained at Chantilly by the Anglo-French trainer Harry Count. Chanteur was reportedly a horse with a strong character: he was the first horse awake at his stable and would "shout" loudly until he was fed. At exercise he refused to exert himself for an ordinarily-dressed stable lad, only showing interest when he was mounted by a jockey in racing silks. When racing in Britain, and later when standing there as a stallion the horse was known as "Chanteur II".
Racing career
1945: three-year-old season
The Second World War led to there being little racing in France in the summer and autumn of 1944 and Chanteur did not run as a two-year-old. In the spring of 1945 he estblished himself as one of the leading French colts of his generation by winning the Prix de Fontainebleau and the Prix Hocquart at Longchamp Racecourse before running second to Mistral in the Prix Lupin. From then on Chanteur was campaigned in the highest class. He finished fourth in the Prix du Jockey Club, fourth to Ardan in the Grand Prix de Saint-Cloud and second to Caracalla in the Grand Prix de Paris. In autumn he won the Prix Henry Delamarre before finishing third in both the Prix de l'Arc de Triomphe and the Prix Royal Oak.
1946: four-year-old season
Chanteur's only important win of 1946 came in May when he won the older horses' version of the Prix Jean Prat over 3,000 metres at Longchamp. In this race he defeated the outstanding six-year-old stayer Marsyas who had won the race for the last two years. He went on to finish second in the Prix des Sablons over 2000 metres and third to Marsyas in the 4000 meter Prix du Cadran. In June 1946, Chanteur was part of an exceptionally strong team of French stayers sent to Royal Ascot. He proved too good for the British opposition in the two and a half mile AscotGold Cup, but finished second, two lengths behind his compatriot Caracalla.
1947: five-year-old season
Chanteur began his final season by showing good form over shorter distances, winning the Prix des Sablons and then moving down to 1500 metres to win the Prix Edmond Blanc. He was then sent to Britain where he won the £5,000 Winston Churchill Stakes at Ascot on 24 May and the £2,000 White Rose Stakes at Hurst Park four days later. At this point he was bought by the bookmakerWilliam Hill, although he remained in training with Count in France. The price was reportedly £70,000, the biggest sum paid for a racehorse in Britain, with Hill explaining that he was buying the horse primarily for his stud potential. At Epsom Downs Racecourse in June he recorded his most significant international success when he won the Coronation Cup, beating Marcel Boussac's Coaraze. At Ascot later that month, Chanteur started the 2/11 favourite for the £11,316 Ascot Gold Cup, but was beaten four lengths by the French-trained four-year-old Souverain in the most valuable ever run in Britain up to that time. Shortly after the race, Hill announced that the horse would be retired from racing.
Assessment
The independent Timeform organisation assigned a rating of 135 to Chanteur in 1947, making him the equal of Souverain as the highest-rated older horse in Europe. Marsyas, who did not race in Britain that year, was not included in the ratings. In their book A Century of Champions, based on a modified version of the Timeform system, John Randall and Tony Morris rated Chanteur the thirty-seventh best French-trained horse of the 20th century and the third-best horse foaled in 1942, behind Caracalla and Dante.
