Kilgariff (P. 565) says "Sarah, or A Donkey Cart Built for Two," was first performed in 1893 by Kate Carney.

Harry Dacre (1860-1922) is listed by Kilgariff (p. 421) as composer of "Daisy Bell," 1892.
Katie Lawrence (1870-1913) scored a hit with "Daisy Bell" ("Bicycle Built for Two") on the London stage in 1893. Kilgariff lists many of her songs (p. 250-251).

Kate Carney (Kate Pattinson)- 1868-1950. Well-known singer-comedian on variety-music hall stages. Kilgariff lists almost 100 of her songs. She also sang American songs, e. g., "Sidewalks of New York" (1894).

Harry Bedford- 1873-1939. A comedian, one of the greats of Cockney songs.
Many songs listed in Michael Kilgariff.

Kilgariff, Michael, 1998, "Sing Us One of the Old Songs," 848 pp., Oxford University Press.

The Bodleian Library has put the date of the song sheet printing of "Sarah" too early- it should be 1893 or later.

"Daisy Bell" may be first, but the two songs are almost contemporaneous.
