I would play all the parts of the song, show them the way it went together. Then I'd basically break down an arrangement - I wouldn't plan endings or beginnings - so they knew everything that was going on. I had the lyrics on a prompter so that I could remember everything I'd written, and I was able to just get into the groove and play with them. I think "Peace Trail" is one of the exceptions, where it's a later take. It just happened really quickly.
