Well,well,well. Some very thoughtout and "creative" suggestions. Thanks, I think. I could make this an audience participation thing and provide a lucky listener with a long, solid wooden staff (ash or ironwood) to prod me and "encourage" those high notes when I give them a pre-arranged signal.

Thanks especially to RichM, CraigS and M.Ted for techniques that don't require bodily damage!

CraigS - There are a few things in my life I hope never to do: 1.Seriously injure or kill a person and 2. Yodel. ;>) Knappo
