Balfe, Michael William - Autograph Note Signed

Irish composer (1808-1870), best known for his opera The Bohemian Girl and other operatic works. Balfe was also a conductor and pursued a career as a singer as well. Autograph note signed, to famous Italian soprano Fanny Persiani (1812-1867) (who created the role of Lucia di Lammermoor in the 1835 world premiere). Balfe is asking her to replace nothing less than Giulia Grisi in a terzetto from his opera Falstaff (Grisi performed at the 1838 world premiere in London), probably in an upcoming concert performance.  One page, 5.25 x 4 inches, signed as Balfe, some toning over the lower border, otherwise in very good condition.
