Now I have carved out a doggy kennel blues practice spot in my garage I am doing much moaning and wailing with my harmonica which as some of the aficionados of the blues will know can sound like a train coming. Well, I happen to live about 400 m from a railway track and when I was huffing and puffing, sucking and blowing, my way through a load of notes which did indeed sound like a train coming I put my harmonica down for a rest and low and behold there was a sound of a train coming but this time I wasn't playing my harmonica. I just thought "Man, the damm thing plays itself sometimes"
