Shortly after Liszt's concert on 11 May 1844, Thalberg left Paris. He travelled to London and gave a concert there on 28 May 1844. At a further concert in London he played a concerto for three pianos by J. S. Bach together with Moscheles and Mendelssohn. He also took part in a concert of Jules Benedict. In August 1844 he returned to Paris where he stayed until 1845. During the winter 1844–45 he gave a piano course for selected students at the Paris Conservatoire. On April 2, 1845, he gave a concert in Paris, playing his fantasies op.63 on Rossini's "Barber of Seville", op.67 on Donizetti's "Don Pasquale" and op.52 on Auber's "La Muette de Portici", as well as his 'Marche funèbre variée' op.59 and the 'Barcarolle' op.60.
