Thanks everyone
Found the site from Google that you refered to, Murray. I remember my dad playing with Trunkles back in the 80s. However, I don't know quite what this reference to electric bones is about!? Someone once suggested making some bones with built in mics but the general feeling was they were loud enough already! Anyway will contact Trunkles and see if they've got any good pics of dad in action.
Great to hear from you Jacob. My dad loved visiting America and I remember him writing to Mr Bones in Boston - he showed me some photos of the two of them together.
Thanks again
Louisa
