The unraced Singing Herbert forged a prolific career as a broodmare for one of Ontario’s leading breeders during the 20th century, the Bill Herbert Stable of Lambeth. Singing Herbert, a 1954 foal by Lusty Song-Betsy Babcock, produced 16 foals between 1957 and 1978 and all were winners. Eight won stakes and three others were stakes placed. Betsy Herbert, a 1959 foal by Alpha Hal, was arguably the best performer in the family. Her stakes wins included the Canadian Standardbred Futurity, Blue Bonnets Futurity, Kitchener (twice), Campbellville, Alliston and Leaside. She was voted CTA Three-Year-Old Trotter for 1962. In 1965, she became the first Canadian-bred to contest the Roosevelt International Trot.

Singing Herbert’s 1960 foal was Dean Herbert, a full brother to Betsy Herbert, winner of the Voyageur, Beaches, Valedictory, Hamilton, Long Branch and Swansea and voted CTA Aged Pacer of 1964. Sis Herbert, a 1961 foal by Replica Herbert, was a double-gaited performer that had her greatest success on the trot. At two she won the Champlain Futurity, Ontario Harness Horsemens and Dufferin and was voted Canadian Trotting Association Two-Year-Old Trotter of 1963. She added stakes wins in the Mohawk and Brantford at three and the Campbellville as an aged performer. Sis Herbert was followed by Becky Herbert, a full-sister who won the Helicopter and Ontario Harness Horsemens at age two and the General Brock at three. The next family member was Rip Herbert, a 1963 foal by Replica Herbert, an aged winner of the Voyageur.

Bucky Herbert, a 1965 foal by Jean Laird, won the Centennial at two, Brantford at three, Jockey Club Maturity and Centennial at four and the Don Mills. Champ Herbert, Singing Herbert’s 1968 foal by Dino Herbert, won the Supertest at three. Her final stakes winner was Sing Away Herbert, a 1971 foal by Nevele Pride, who won the General Brock, Oakville, Mohawk, Supertest and Scarborough in 1974. Singing Herbert’s stakes-placed performers included the double-gaited winner Horton Herbert, Stoner Herbert and Supersam Herbert.
