Well, I guess I might be an opera snob; years of religious attendance of opera performances around the world, and university study (B.Mus in Opera) have been known to cause that condition. Certainly to be a tenor, which is only a descriptor of an individuals preferred tessitura, does not require that one be an opera singer. However, I dispute calling individuals like Watson and Lanza, however talented they might be "opera stars".
Lanza sang only one or two complete roles on stage to my knowledge, though compared to Watson, his years of study and work with the Bel Canto Trio certainly give him a certain pedigree. Two roles, and I think one was a student production, hardy a career in opera makes, (though I wish it did because at 21 that’s just about all I’ve got!)
Mario did portray opera singers in the movies, but is a person who portrays a medical doctor on TV necessarily an MD in actuality? Lanza’s lasting fame comes from his movies and recordings of popular songs. Certainly most persons of my generation know him better as a singer of songs like “Be My Love” than Verdi arias. As a singer of popular songs with a more “classical technique”, there are only a handful or so that can be considered his peers and perhaps but four who have done it better Joseph Schmidt, Richard Tauber, Jan Kiepura and Frtiz Wunderlich. Needless to say, I don’t think it’s fair to compare Lanza with Watson, and certainly not with the likes of Wunderich, Domingo, Pavarotti or Corelli.
As for having "the pipes", I think that is purely a matter of opinion, but I like my singers to be able to give recitals and sing onstage without amplification. Otherwise, to relate it to skating, it would be like doing your jumps in competition with the assistance of a harness.
When it comes to singers, whoever gives you pleasure can be your star. It’s all a matter of taste and preference, opera junkies just tend to think our opinion is worth a little more, and I think that might just say more about us than the individuals we critique.
Happy listening Ladskater!
