It was during his first journey to London that Joseph Haydn made the acquaintance of Carlo Francesco Badini, who wrote the texts of his duets Saper vorrei se m’ami (Hob. XXVa:2) and Guarda qui che lo vedrai (Hob. XXVa:1). Badini, who had long been active there as a librettist at the Italian opera house, also wrote the text for Haydn’s final opera, L’anima del filosofo, ossia Orfeo ed Euridice, in 1791.
