ok first off Yes he could have, NO he wasnt to skinny.
This topic has been brought up in 60 different ways and always ends in a fight. You seen what he was trying to do, you seen him working as hard as he could. What was the song where he kept saying.... oh oh... i know what its called. KEEP THE FAITH.
We get the rehearsal we get to see what COULD have been. There is no faith in the fans even before his death that he could have done this. kinda makes me mad at the lack of faith the "Fans" had in him from the get go. Everyone was so worried about the concerts being canceled....guess this didn't disappoint you.
