By April 1834 the opera had received over 100 performances in Paris. Nourrit sang the role of Robert until 1837, when he was replaced as premier tenor at the Opéra by Gilbert Duprez, whom, however, Meyerbeer did not like in the role; nor did he approve of an alternative, Lafont. However, he was impressed by the newcomer Mario (Cavaliere Giovanni Matteo di Candia), and wrote for him a new aria for Robert which was performed at his debut in the revival of the opera on 30 November 1838. Mario's debut was the launch of his very successful career. Others singing in the 1838 revival included Julie Dorus-Gras (Alice), Prosper Dérivis (Bertram) and François Wartel (Raimbaut). By Meyerbeer's death in 1864 the opera had been performed over 470 times in Paris alone.
