OK, I'm not a huge fan of opera, but this is simply a masterpiece song sung by masters (may they RIP). Brindisi "The Drinking Song" from La Traviata, sung by Dame Joan Sutherland and Luciano Pavarotti. Nfi what they're singing, and it's probably in Italian (not that it would really matter; it is opera after all ) but it is the only opera song I get a buzz out of listening to. Enjoy (or not rofl).
