It is possible to play the Beginning/Chorus part of the song using normal
tuning. Unfortunately, it's going to require a long stretch for the D#/Eb.
It would look something like this:
G5 D# Bb5 C5 N.C.
1|------3-3-----------
2|------4-4-----------
3|------3-3--3---5--0-
4|-5-5--1-1--3---5--0-
5|-5-5--1-1--1---3--0-
6|-3-3--------------0-
The last strum of open zeros can also be played as just another C5 . You can
also get rid of that long D# stretch for the 1's by just playing (xxx343).
Also, Dave plays the verse like the second tab posted here, but it sounds
pretty bad on an acoustic. To make it easier, you can just play this
progression:
G7 F7 C
1|-3---1-----
2|-3---1---5-
3|-4---2---5-
4|-3---1---5-
5|-5---3---3-
6|-3---1-----
It's not perfect, and it's not how I think they play the song, but it sounds
decent. Finally, somewhere I saw it posted this way for the pre-chorus, and
it's definitely right. The secret is that the last chord played is a C9 , an
uncommon chord. It goes something like this:
A#5/F G C9
1|--------------3-3-3-3-3-3--0-0-0-0-0-0-0-0-0-0-0-0-
2|--------------3-3-3-3-3-3--3-3-3-3-3-3-3-3-3-3-3-3-
3|-3-3-3-3-3-3--0-0-0-0-0-0--3-3-3-3-3-3-3-3-3-3-3-3-
4|-3-3-3-3-3-3--0-0-0-0-0-0--2-2-2-2-2-2-2-2-2-2-2-2-
5|-1-1-1-1-1-1--2-2-2-2-2-2--3-3-3-3-3-3-3-3-3-3-3-3-
6|-1-1-1-1-1-1--3-3-3-3-3-3--------------------------
Hope this helps.
