To me, he is the greatest tenor of all time, and yet I can find only
limited info about him on the internet.

I am interested in how tall he was, since I have been told that
only 'big' tenors have 'big' voices (ie, Correlli, Domingo). While
Jussi was not a dramatico tenor, he had a huge voice for his type --
yet he looks short. I also understand that Caruso and Mario Lanza were
short.

Anyway, I have seen him in the Voices of Firestone, and though he does
look heavy-set, he did not look very tall.
