Sunday Morning Opera: Simon Keenlyside August 6, 2017August 3, 2017 SJ Reidhead Baritones, CULTURE, Music, OPERA, Simon Keenlyside There is only one word that describes Simon Keenlyside: elegant. His birthday was on Thursday. I won’t mention his age since he and my sister were born the same year. I do love his Mozart. I think I may enjoy his Mozart more than any other baritone.
