I'm sure if you were to e-mail Mr. Morrison he'd be happy to respond to you. That is really the mark of a true actor, one who is willing to respond to and nurture an interest in ones own career and in the artform they represent. I have sent letters and e-mails to a dozen high profile musical theatre composers, actors, actresses, designers, directors etc. They have all been so very down to Earth and reasonable.
They just want to learn and to teach and to understand. Putting them up on a pedestal is inappropriate, rather than hero worshipping, just learn to respect and appreciate their work. It is much more satisfying.
