Robert Goulet is in hospital waiting for a new lung.
See here. The article mentions his performing in Camelot, and I remember seeing it on Broadway with Julie Andrews, Richard Burton and Roddy McDowell when I was in school. I'll never forget him singing "If Ever I Would Leave You."
I hope he gets better and is around for a long while yet.
