Murray,

You would be aware that the Australian character is such that one would never enquire as to how you actually damaged your finger(s), but that should not stop people from speculating (loudly) about the fact. So, I won't ask.

There is a shareware program known as HARPING which in my view is a fun way to give blues harp a try. You may be familiar with the ZDNet site, which is where I got it. The local service is zdnet.com.au. HARPING has 8 or so tunes you can play along with, shows the blow and draw note numbers and allow you to change key and tempo. As I recall you can import any standard MIDI file to play along with as you wish.

Enjoy, John
