In 1972, she made her first appearances at Covent Garden and the Lyric Opera of Chicago, both in the role of Violetta. That same year she returned to the Met as Elisabetta in Don Carlo with Franco Corelli in the title role, and sang the title role of Bellini's Norma in Philadelphia. In 1973 she returned to Chicago to perform the title role in Donizetti's Maria Stuarda with Viorica Cortez, appeared as Violetta in Philadelphia. She performed at the Met as Bellini's Norma, opposite Carlo Cossutta in his Met debut as Pollione and Fiorenza Cossotto as Adalgisa.
In Bellini's Norma, Caballé recorded both the title role (for RCA Red Seal in 1972, with Domingo as Pollione) and later the role of Adalgisa, to Joan Sutherland's Norma in a 1984 Decca recording conducted by Richard Bonynge. Although Bellini conceived the role of Adalgisa originally for a soprano, it is usually now sung by a mezzo-soprano. Caballé was one of few sopranos to have recorded the role, although she was over 50 years old at the time of the recording in 1984. In 1986 she also took a role in the biographic film Romanza final, directed by José María Forqué.
