The first in my new series on Irrelevant Postings, this one about the Johann Sebastian Bach - "Coffee Cantata" BWV 211, complete with full lyrics, as well as the video of a performance of the piece by a string orchestra and two vocalists.  How irrelevant is this for me?  Well, I don't drink coffee, never have, probably never will, so it's totally irrelevant for me.  But I sent the link to my brother, who is an opera fanatic, so it might be quite relevant, or at least a little bit interesting, for him.
