For our Christmas services at NewSpring Church, Ken Wilson (avclub.us) took some Reason loops/beats, loaded them into the iPhone app Beatmaker (intua.net), and then we used them to "DJ" opening sets as people arrived prior to the service.
Ken and Daniel tagteamed it at our Anderson Campus (vimeo.com/2601768). I was on at our Greenville Campus. I replaced a few of Ken's original samples with some of my own (handclaps, Charlie Brown, George Carlin, more low-end tomfoolery) for a slightly different flavor.
