I've been playing Number Twelve Train for awhile. I am trying to do a Josh White thing with the intro where he makes the guitar sound like the train starting, then slow staccato E chords strumming and muffling almost immediately. Then you pick up speed. He does this thing with a steady flow of eighth notes on the E string using his thumb. Then he throws in a series of 'train-whistle' double stops played on the E and B strings with the first two fingers. That takes manual coordination! Then he slows the train down and goes into the song. Like I said, I am attempting this, I am no where near his expertise on the guitar!
Peace. Rustic
