Tush

take this for example;
Shuffle in E:
[A]|-2-2-4-2-2-2-4-2---|
E|-0-0-0-0-0-0-0-0------------| Etc.

But the G in the intro and at the beginning of the verses is more of a riff, and is played like so:

e|------------------------|
B|------------------------|
G|------5-3-5-3~-5-3-5-3~-|
D|-5x-x-5-3-5----5-3-5----|
A|-5x-x-------------------|
E|-3x-x-------------------|

And that's the explanation, here's the chords:

I been [G]up, I been down.
Take my word, my way a[C]round.
I aint askin for [G]much.
I said, [D]lord, take me downtown, [C]
Im just lookin for some [G]tush. [C]   [C#]      [D]

I been [G]bad, I been good,
Dallas, texas, holly[C]wood.
I aint askin for [G]much.
I said, [D]lord, take me downtown, [C]
Im just lookin for some [G]tush. [C]   [C#]      [D]

Take me [G]back way back home,
Not by myself, not a[C]lone.
I aint askin for [G]much.
I said, [D]lord, take me downtown, [C]
Im just lookin for some [G]tush.
