Bacquier was definitely one of the great baritones!

That's an impressive musical life span, for sure. Only retired from the stage in 1994, yet taught further on, and recorded even in 2007, it seems.
A great baritone, I was fortunate enough to see him at the Metropolitan in the 1970's. I wish that Saint-Saens' masterpiece, Henry VIII was revived for him- he would have been perfect for that demanding and grand role! thanks.
