Adam is always putting himself out there.
Let's go to NYC to give Charl some love re: his Tony nomination.
Ooh, I want to see some plays.
Ooh, I want to see some more plays.
Everyone says, Adam, you need to stay in town for Broadway Bares.
I think I will.
Hmmm. Adam is in town, and the boy was outspoken about singers who can sing re: Le Miz.
Adam has been doing high profile pride events/benefits. Maybe he would be a nice surprise.
Adam attends rehearsal with Charl & other friends.
Hey, Adam, want to sing?
Only if it fits with the show.
by the way, Charl, et. al. say to TPTB, have you heard him belt out the SSB? No, he doesn't need instruments/music, so it would be easy to fit him in.
(quick run to Alexander McQueen)
The rest is history.
