I was sorry to hear yesterday that he had died. I had the privilege of sharing a concert platform with him once, in Britten’s St. Nicholas at the Barbican with the Tallis Chamber Choir and (I think) the ECO. I certainly heard him sing on other occasions, most recently at the ROH last year.
I have a CD of children’s songs, Minimusic, performed by him with more intelligent and musically interesting accompaniments than is usual. I realise I haven’t recommended it here before, so I’m doing so now.
