Manuscript Receipt Signed, for payment of £126 for her performances at Concerts of Antient Music in 1813. 4 x 9 inches, some old repairs to verso, of good appearance. 9 March 1816. Jane Jackson (1776-1858), first appeared at a London concert on 25 April 1798, and sang as Miss Jackson at the Concert of Ancient Music in 1800. That same year she married the composer Francesco Bianchi; while Mrs Bianchi she often sang at Windsor in the presence of George III and Queen Charlotte. She and Bianchi soon separated, he died in 1810, and she married William Lacy, bass singer, in 1812, singing as Mrs Bianchi Lacy until 1815. Considered one of the finest interpreters of Handel as well as a good pianist and painter, she was noted for her grand, simple style and perfect delivery of Italian. Through her friendship with R.M. Bacon, portions of Bianchi’s celebrated manuscript theory treatise were published in early volumes of the Quarterly Musical Magazine.
