Okay, I know this is an old song...actually it's really old, but it's
still a great song none the less.  I don't know the actual way to play
it, but I think this is very close.
----------------------------------------------------------------------
Normal Tuning (E,A,d,G,b,e)
Bass and Guitar (Not full)

BASS (Played real phat and muffled tone)
G)-------------------|--------------------------|
D)-------------------|--------------------------|
A)----------5--------|----------5---5h7-5h7-5\--|
E)--7-7-5h7-----7\---|--7-7-5h7-----------------|
That's the main bass part.  It's pretty much the same throughout the
song.

GUITAR  (Overdrive...but not too gritty)
e)-----------------------------|
B)-----------------------------|
G)--6-6-6-6-6-6-6-4-2-2-2-2-4--|
d)--6-6-6-6-6-6-6-4-2-2-2-2-4--|
A)--4-4-4-4-4-4-4-2-0-0-0-0-2--|
E)-----------------------------|
...And that's pretty much the guitar part...I'll have other parts
later and other Beatles songs in the near future.
                                 Have a good one,
