I just heard this live acoustic version and I must say, sounds great! I did all this
by ear. I found 3 good ways to play the intro but I put the one that I feel works the
best with the acoustic. Please listen to the acoustic version before giving me a rating,
I think you might find it works well. I'm about 90% sure this is correct. Thanks!
