Oh no worries. Youtube is an aggressive place
I mean to ask, too. What is your sound set up? It was solid quality. I've heard the DSLRs aren't the best for sound and don't have audio input jacks.
I used a sennheiser boom mic, and a record device by M-Audio: Micro Track II. I've been asked this question a lot, so I'll write a blog with all the links and stuff in. I'll message you when its up!
