Did pavorotti sing with lanza in the movie caruso?

Mario Lanza, not Luciano Pavarotti, starred in the 1951 biographical musical film about Enrico Caruso titled "The Great Caruso." Lanza portrayed Caruso and sang all the operatic arias himself, with the exception of some of the high notes, which were dubbed by the Italian tenor Giuseppe Di Stefano. Therefore, Pavarotti did not sing with Lanza in that movie.
