Thomas Hampton was born at Blaisdon in Gloucestershire (baptised March 1844), and probably worked on the canals for a while. By 1870 he was living in Hereford, being married there that year. He died in 1896, still resident at Bath St. Hereford. He left a manuscript containing tunes, which is now in the possession of his great-great granddaughter, Becky Dellow, who is researching both TH and the tunes. Although the manuscript was compiled in Hereford, Becky believes some of the tunes were remembered from TH’s childhood in Gloucestershire.

Mama’s Little Pet Waltz and Waltz (3)
Handwriting evidence shows that the first nine tunes in the book were compiled by Walter Soobroy, who lived close to Thomas Hampton in Hereford. It seems likely that Soobroy was teaching Hampton and used the tunes for that purpose. Tunes 6 and 7 in the ms (not transcribed here) are exercises on scales.
These tunes are likely to have formed a set, being played ABBA, as the second ending of the second tune leads naturally back to the first. (See version to play)
Mama’s Little Pet Waltz is attributed in the manuscript to H Farmer, probably Henry Farmer, (1819-1891), a composer and owner of a music warehouse in Nottingham.
