We will be using royalty free music when we decide to put the DVD out for sale. This was just to show you guys what we have been up to and give you some insite to what to expect from the DVD. As far as the light goes we use Magnalights hand held with a rheostat wired in to it. And I'm not sure who Mark Davis is but the older guy in the clip towards the end is my dad Ron Skinner. Glad you guys our enjoying the clip that's just a sneak peak at what's to come so stay tuned. God Bless Seth
