Whether or not a performance was stellar or not, Sam respected everyone that got up on that stage to sing. That required quite a bit of courage. He couldn't do it. For one, he really couldn't sing (at least in his mind) and for two, he was terrified.
He couldn't help but laugh at that. "I've heard worse." he said amicably. Talking was actually easier with someone he knew, even if it was just from passing.
He grimaced at the nickname. "Oh please not that. Sam is just fine." he said, but it was obvious that he wasn't mad. He didn't really like any sort of nicknames, and Sammy was quite at the top of that list, but it hadn't been done to spite him and hey, at least he had been remembered.
