oh dear, I hope the rumors that he can't speak at all are not true
For someone who so likes to articulate his thoughts the way LB does this would have to be particularly frustrating....
I have to say when I watched him on the school video, the way he approached the chorale director to shake hands/hug, I was surprised not so much that he didn't speak (given what we knew about the vocal cord damage) but that he didn't even mouth any words at all....
Just seemed sort of out of character in some way.
I really, really hope for him that if this is true there is a way to work to get some ability to vocalize back.
