It doesn't matter who your great great grandpa is

I went to a very bad concert last night, in all my short life I've never had an experience quite like it. For chapel credit, we could go to this concert. The guy is the great great (great?) grandson of one of the founders of Biola, R.A. Torrey. Yes, and he's also the founder of the infamous and slightly ridiculed Torrey program. So Thomas Torrey (yes that was the grandson's name) was singing at this concert. He gets up on stage and mumbles something into the mic, which I doubt anyone could understand. Partly because he talked too fast and partly because his mic volume was turned down way too low. Then he starts to sing, and again we couldn't understand a word. It just sounded like random moaning. The poor guy looked in pain, and slightly scared. He kept his eyes squeezed shut tight the whole time with his face frozen in a sort of grimace. He could have been worshipping, but how could anyone tell if it was a worship song? He had a paper with the lyrics taped on his microphone stand and he didn't move from one spot the entire time. He hopped from song to song without any sort of intro or break between song, which didn't really matter because they all sounded surprisingly similar. His guitar playing was off from his base player's rhythm and the drummer was a bit behind, I'm thinking it might have something to do with the bad sound job. It was entertaining... but not in the way it was meant to be I'm guessing. All this to say that:
A) it's probably best to hear the guy before you ask him to come sing in front of hundreds of people. B) good sound people are invaluable. C) stage presence is essential. D) It's a good idea to learn your own lyrics E) it's not always the best when all the songs sound the same. F) Just because you have a famous great great great great great granddaddy doesn't mean you've got the famous genes.
