Trey in fact did have a 'Greenish-Teal' Languedoc for Sets II and III, I didn't notice it in the first. Now friends of mine said that it was his 'Time Turns Elastic' guitar, but I disagree; I think it was a gift for Christmas from Paul to Trey and he decided to bust it out, Paul Languedoc was in attendance so this is my theory, jump on it or not; but one cannot disagree with the fact that Trey definately was playing the entire 2nd and 3rd Sets with a 'Green-Blue' guitar!
