I've just created a new page on which Lanza's live (1949) performance of "È il sol dell’anima . . . Addio! Addio!" from Verdi's
Rigoletto can be compared alongside renditions by Pavarotti and Björling.
To make things fairer, all three versions are live performances, and the tenors are of similar ages here: 28 (Lanza), 31 (Pavarotti) and 34 (Björling).
Of course, it should be borne in mind that Lanza's singing partner here---18-year-old amateur Mary Jane Smith---is certainly not in the same league as Renato Scotto and Bidu Sayão, Pavarotti's and Björling's celebrated sopranos, respectively :) Pavarotti's and Björling's renditions are also taken from complete performances of Rigoletto, giving them a considerable advantage over a concert performance by a tenor who had never sung the role of the Duke on stage.
So how does the young Lanza stack up in comparison with the more experienced Pavarotti and Björling?
