Call Boy's dam, Comedienne, a daughter of the Irish Derby winner Bachelor's Double, had been bought by Curzon for 130gns.

Call Boy made his racecourse debut in the prestigious July Stakes at Newmarket in which he finished third to The Satrap and Sickle.

In the Champagne Stakes at Doncaster he produced a strong finish to reverse the form with Sickle but narrowly failed to catch Damon.

[1] On his three-year-old debut Call Boy started favourite for the 2000 Guineas at Newmarket, despite the fact that he was "evidently backward in condition", but was beaten a short head by Adam's Apple.

[4] In the days before the photo finish was introduced results were decided solely by the judge, and on this occasion there were some who felt that Call Boy had been unlucky not to have been given at least a share of the prize.

[7] The race took place on a wet and "dismal" day in front of a crowd which included the King and Queen as well as the aviator Charles Lindbergh.

Curzon who attended the race against doctor's advice, was obviously unwell ("pale and trembling"[11]), but managed to lead the colt in and accepted the winner's trophy.
