Wow, he says some things, so Michael got married with Debbie to be in line with Arabian culture for doing business. Never heard this before. Totally new. What I knew was that his Mother asked him to marry Debbie when Ms. Katherine found out that she was going to have a baby. Now I would rather buy this explanation than Frank's.
About the MJ on stage, I bet it was amazing for Frank to be with him on tour and see him totally transforming himself while on stage and being just like everyone else behind the curtains. What a privilege Frank had, lucky him!
