It was before my time, so the student in the photo would not have been Henning, anyway. Still, given the accompanying text, rather glad I was not there.
Of course, it is but an alumni magazine, so it is probably unfair to insist on so stern an interpretation of the sentence. Allow me, for old times’ sake, to play Devil’s Advocate with a tendentious excision: Each of the men pictured here (except the student, second from right) . . . helped shape contemporary music in his own way. Bad luck, Wm Appleby, for being the one party in the photograph who shaped no contemporary music.
There you are, basking in the light of the Great Men, though.
