Oh, I have no end of Irish drinking songs, but I wouldn't feel very Oktoberfesty singing them .... Not that I actually know anything about Oktoberfest ....

As for German-language songs - of course, those would be best, but I'm not up for the challenge, tbh. I'll brush up Beer Barrel Polka, I've got The Happy Wanderer, and I'll learn Wooden Heart, since when I gave it a listen on youtube, I realized I've already got the melody floating around in the back of my wooden head. Add a polka or two on fiddle, and that'll do the job. They're not expecting a full Oktoberfest program, just a tip of the hat - one of those funny little German hats with the feather in it - in the direction of the occasion.

Thanks, again!
