Led Zeppelin - In My Time Of Dying

Opening riff: (set tone to "crunchy" :-))

e|-------------------------------|---------------------|
B|-------------------------------|---------------------|
G|-32^0-2/3/5~--0-32^0-(0)/12~---|-32^0-2/3/5~-0-31^0--|
D|-32^0-2/3/5~--0-32^0-(0)/12~---|-32^0-2/3/5~-0-31^0--|

Another part:

e|----------------------------|---------------------------|
B|----------------------------|---------------------------|
G|-0-3-5---0-(5)/7-0-(3)/53-0-|-0-3-5---0-(5)/7-0-(3)/5-3-|
D|-0-3-5---0-(5)/7-0-(3)/53-0-|-0-3-5---0-(5)/7-0-(3)/5-3-|
A|----------------------------|---------------------------|
E|----------------------------|---------------------------|

Repeat that once.

Yet another part: (a little faster than previous progressions)

e|------------------------|--------------------------------|
B|------------------------|--------------------------------|
G|-(3)/7~-0-(3)/5^0-3-0-:-|-/12~-0-(3)/5^0-3^0-:--5-(hold)-|
D|-(3)/7~-0-(3)/5^0-3-0-:-|-/12~-0-(3)/5^0-3^0-:--5-(hold)-|
A|----------------------^-|--------------------^-----------|
E|----------------------|-|--------------------|-----------|
repeat repeat

Now, right after that last 5-5 power chord, there`s a little
piece that I can`t figure out. It leads to this fast part, tight
with the drums:

e|---------------------------------------------------------|
B|---------------------------------------------------------|
G|-(2)/32^0-(2)/32-0-(2)/53-0-(right here I usually play some)
D|-(2)/32^0-(2)/32-0-(2)/53-0-(fast 0-0 "fills"; 3 or 4, drums)
A|---------------------------------------------------------|
E|---------------------------------------------------------|

Repeat several times.

I`m not sure what the standard nomenclature is, but here is what
I meant:

(X)/Y : Start slide at X fret, slide up to Y fret.
X^Y : Pull slide off strings.
X~ : Hold and "wiggle" slide for a tremolo effect.

This is my first tab, so please refrain from flaming, although
corrections are more than welcome. At the very least, your
friends
will recognize this tune. I recommend listening to the song, of
course. Have fun!
