Troubles, troubles, troubles everywhere! I’m alluding here to the old B.B. King hit way back when, and I seem to recall the Waverly Brothers singing it, too. Anyhow, I’ve been trying without much success to post a slideshare presentation–which precedes this post. I posted one successfully two years ago and this one isn’t so good I’m afraid. I hope someone will alert me and/or forgive me if you weren’t successful in viewing the lunch in wayra post that appeared before this one.
