Also: Pavarotti is awesome y'all. I'm not afraid to admit that Nessun Dorma has tugged a few heart strings in the past.
Oh yes, certainly. Nessun Dorma has pretty much become (or became, already) the "trademark" of Pavarotti. There's nobody on this globe that does not know Pavarotti's version of Nessun Dorma.
He's performed the song better than the album, or any other concert (or Tenor), in the Paris 1998 concert of The Three Tenors. The end was definitely perfectly done - he held the last notes so long, it was superb; that includes 1:12-1:22 as well. As if he has infinite lung capacity.
I highly recommend you watch it, Queenofdisco. Here's the link:

Generally, this concert has the greatest songs, performed at their very best. Dicitencello Vuie is highly recommended, too.
