Easy Ten Points! How?

I go to a really big church (New Life Church) and my youth group is around 500 people. Basically, we do worship with a band (Desperation Band) for about an hour and then we sit down and listen to our pastor. There is a guy that I see every week when I go who always worships in the same area that I do. It's such a big church that I don't even think he notices me. However, I might be interested in getting to know him more. What do I do to get his attention? I'm pretty shy when it comes to meeting new people. So when would be a good time to say hi? I think it's a bit awkard if someone says hi randomly? So... what are some excuses to use to talk to him or what can I do to get his attention?
