No Pics im sorry,
but a guy previously in our band had a really sore throat, but still had to perform,
he acquired a bladder out of a wine cask, some plastic hose and a foot car pump, and lots of electrical tape and of course his whistle,
I wasnt there at the time but by all reports it worked fine, all but for the occaisional strange squark,
he nick named them the Austruillean Pipes 
after all all ya need is wind, air pressure and a whistle
oh
and a lot of patience
