A John Jacob Jingleheimer Schmidt Headache

Wow - I ended up with a headache today like none other; I think it's days like this that keep the Tylenol people in business. I got the brilliant idea over the weekend that it would be fun to have my little music students (K-3rd) do some activities with music and volume -- singing softly and loudly, playing instruments softly and loudly, etc. Anyway, I decided that we'd sing the "John Jacob Jingleheimer Schmidt" song and then do another similar activity with instruments -- drums, mini cymbals, triangles, etc. To make a long story short, the activity was a huge success -- the students loved it and I met the objectives that I had set for the day. However, after 2 hours of hearing ""John Jacob Jingleheimer Schmidt - LA LA LA LA LA LA LA!!" I ended up with the most awful pounding headache that I've had in a very, very long time....
