I found this interesting article from Canada's Globe and Mail. Adam Blanshay
"Noel [Coward] and I were in Paris once. Adjoining rooms, of course. One night, I felt mischievous, so I knocked on Noel's door, and he asked, 'Who is it?' I lowered my voice and said 'Hotel detective. Have you got a gentleman in your room?' He answered, 'Just a minute, I'll ask him.'" (Beatrice Lillie)
Blanchay sounds like a decent guy, JFL Theatricals is involved with many new shows like Made in Dagenham and I Can't Sing! plus plays like Ghosts and Mojo so he's working with experienced producers like Sonia Friedman, Stage Entertainment etc before he can branch out as a lead producer.
