I can't say that I'm much of a fan of opera, but I play string Bass in a Community Orchestra. We play all kinds of music - classical, pop, music from 1900 - today. i also enjoy singing along with YouTube videos - I've got a 2.5-3 octave range (not too many people do) - Baritone to medium tenor - or as I like to put it in terms most people can understand - Josh Turner (not his deepest) to Josh Groben. I can do a respectable cover of Art Garfunkel singing "Bridge over Troubled Water". I can do the Star Spangled Banner.
Scott, I loved to sing too and did HS Glee Club (men's, whole choir, madrigal), and was also baritone to 2d tenor (not all of 1st). Our choir master was probably the most beloved teacher in HS, and we competed and won things. I sung in church too (not the choir, just from the pew).
Once in elementary school, our class did some singing, and I got a short solo (standing up) as soprano. Man that was like a lifetime ago.
30 years of tobacco killed my voice. So I only sing to myself anymore (talk to myself too

).
