Harry Greenbank (11 September 1865 – 26 February 1899) was an English writer and dramatist best known for contributing lyrics to the successful series of musicals produced at Daly's Theatre by George Edwardes in the 1890s.
He continued to write such small-scale pieces over the following couple of years, both for the Savoy (Mr. Jericho in 1893 and Old Sarah in 1897) and for the Lyric Theatre, where Horace Sedger asked him to supply the English lyrics to F. C. Burnand's adaptation of the French operetta Le coeur et la main (Incognita).After that, George Edwardes put Greenbank together as lyricist with music director Sidney Jones and dramatist Owen Hall to create the hit musical comedy A Gaiety Girl in 1893.
He also contributed additional lyrics for The Bric à Brac Will (1895) and, posthumously, a song for the London production of A Chinese Honeymoon (1901), "Roses Red and White".
Greenbank was often in ill health, and during the production of A Greek Slave, he moved with his wife and son to England's southern coast in an attempt to regain some strength.
He died there while writing lyrics for San Toy, and the piece was completed by Adrian Ross, who, with Greenbank, was largely responsible for establishing the post of lyricist (as opposed to librettist, or co-writer) in the modern musical theatre.
