@Reminiscence- My wife and I attended a free concert by the Navy orchestra and the narrator was a bass-baritone. He was the official narrator for several presidential inaugurations, including Barack Obama's 2012 ceremony. We couldn't believe how deep and resonant his voice sounded over a relatively small PA system. I almost thought it was a recording, because it was so commanding.
He sang a song from Les Miserables and it sounded almost operatic. Someone told us during the intermission that he also performed Old Man River from time to time. I enjoy a good operatic tenor, but I think bass-baritone has become my favorite voice in a choir.
