Bod-aych-ran we heard once, and were polite enough not to laugh because, well, you never know...

Cool festival idea, assuming of course that other instruments are welcomed to make the drum sound within context. Drums are a huge part of many cultures and should be welcomed.

An aside here: If school children were taught rhythms they would be less handicapped when they seek out music lessons later. They'd also work off some steam (assuming they actually got to play drums), and (gasp) have fun.

Peace, Mooh.
