I saw him as Max about a year and a half ago. I thought his acting was brilliantly funny, but his singing was sub-par (for me). However it didn't take away from the show because Max does not need to be a fantastic singer. I didn't get to meet him, but from what I hear he was a very gracious man.
"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
