Derek, at the Surrey Shadows Club the other night I was standing next to you as you did one of those piercing 'fingers in the mouth' whistles.
My question is (and I've been trying to find out since boyhood) - how do you do it?
With the music playing all the time it's never easy to have a proper conversation, so you'll have to describe in words what the trick is.
From observation, it seems that the index and third fingers go in the mouth, but where does the tongue go, and is there any other 'magic' that needs to be mastered?
