Don't worry, Blackcatter. I was in no way offended. Besides, if this damn mouthpiece doesn't come off tommorow, I may have to resort to Guest's advice and use a hammer to flatten it. So far it's been totally unresponsive to hot water.

But, hell, I've learned a lot today. Like Chiff and Fipple, how much an Overton costs, that a tinwhistle has a third register... I even used the translation facility on this site to check how a pertinent phrase in your last post sounds in French: "Je vais aller *** de f moi-meme plus tard ce soir" is what came out. Sounds good!
