The real challenge for me was working out the “back and forth” lead guitar parts. This is always fun in our live shows, and Clint and I were pretty keen on working in some harmony guitar parts, and trading licks. We would write the parts between sessions and teach them to each other just before the recording started. If we didn't record it right then, we would surely forget before the next session! I think it turned out great, if not exactly spontaneous.
