He was the musician when Headington Quarry were encountered by Cecil Sharp on Boxing Day 1899. Sharp noted down his first Morris tunes from Kimber's playing. Subsequently Kimber acted as Sharp's informant on the Headington Quarry Morris tradition, and as his assistant at lectures - Sharp would lecture on them while Kimber demonstrated the dances and played the concertina.
Kimber's Anglo-concertina playing - making use of the left-hand to add simple but effective chordal and rhythmic accompaniments - showed great vitality and lightness of touch. The recordings made of Kimber, many of which are now available on CD, are among the very few recordings that exist of English traditional concertina players, and have been very influential on later twentieth century exponents of the instrument.
In 1894 Kimber married Florence Cripps, and they had three children. "Merry" Kimber built a house for himself in 1911, which he named "Merryville". His first wife died in 1917, and in 1920 he married again, to Bessie Clark.
