There are a lot of different versions of this intro on the forum, but after seeing them live I am pretty sure this is accurate. Once you get the timing down hopefully it will make sense. Tuning: Standard D/A Aadd4 D/A G/A D/A Asus2 D e|--10----9-------5-------7-----5------0------2-------------| B|--7-----10------7-------8-----7------0------3-------------| G|--7-----9-------7-------7-----7------2------2-------------| D|--0-----0-------0-------0-----0------2------0-------------| A|--0-----0-------0-------0-----0------0------0-------------| E|----------------------------------------------------------| *The two variations of D/A I feel should not be substituted, i.e. don't use the D/A chord in place of the second one or vice versa. The way I saw it live it was walked down in that manner giving it a crisp bright D/A in the beginning. Peace and Merry Christmas!
