Through the Eton College Chronicle archives I found an issue from June 6, 1918, that has Michael’s name (well his last name, but I know it’s him) a few times.
First there’s a review of a speech Michael gave and it says he didn’t sound interested in giving the speech, and now we know that it’s probably because he was losing interest with Eton at this time.
But also Michael and I guess the other members of Macnaghten’s House recited poetry and performed excerpts of plays. Michael recited the poem “Amaturus” by William Johnson Cory. He played a character called Mr. Sneer in a scene from the play “The Critic” by Richard Brinsley Sheridan. I found an excerpt online of Hugh Macnaghten’s book “Eton Letters 1915-1918” (I don’t own the book) that mentions this event and Macnaghten wrote, “Michael Davies as Sneer one of the very best performances I have ever seen.” Another play excerpt was performed from Act 2 Scene 4 of Molière’s play “Le Médecin malgré lui” or “The Doctor In Spite Of Himself” and Michael played Lucinde, daughter of Geronte.
Here is a link to the issue:
