Peter Horton's preface makes reference to William Husk's observation that Smart was interesting if unoriginal. That's probably true, but the same could justifiably be said about much music written for the Anglican church. Smart in G evening canticles are just that. It would be overstating the case to claim that Smart in G was an early-Victorian masterpiece, but given the competition (Wesley in E aside) it's as good as it gets.
Henry Smart was born in London, and was the nephew of Sir George Smart, the eminent conductor and Organist of the Chapel Royal. He studied law before turning to a career in music. From 1831-36 he was Organist of Blackburn Parish Church, but returned to London to take up the post of Organist at St Giles-without-Cripplegate. Later he moved to St Luke's, Old Street, and finally in 1864, to St Pancras New Church. For the last fifteen years of his life he was totally
blind and dictated his compositions to his daughter. Several of his hymn tunes enjoy popularity today and appear in a number of modern hymn books.
