This is the first single from the Spinal Tap album "Break Like The Wind".

The opening riff is just based on the open A and D chords:

  A        D5 
---------------
-2--2---2-3----
-2--2---2-2----
-2--2---2-0----
-0--0---0------
---------------
 
This is repeated till the line "You won't behave the way a big girl should"
when this chord sequence occurs.

E F#m G

For the chorus it is just a permutation of the opening riff with a slightly
different timing for the first two chords.

For the bridge with lyrics "No more sniffing strangers..."  

       2X         2X          1X
----------!-----------!----------!
----------!-----------!----------!
----------!-----------!----------!
-5-5--3---!-7-7--5----!-9-9--7---!
-3-3--1-3-!-5-5--3-5--!-7-7--5-7-!
--------1-1--------3--!--------5-!

The not terribly devastating solo goes like this:

                                  s 
------------------------------------!
------------------------------------!
-----2-4b(6)--4b(6)-4b(6)r(4)-2--7-!
--2h4-------------------------------!
------------------------------------!
------------------------------------!
 
 
----------------------------------------------!
----------------------------14-------------15-!
-------14-16b(18)-16b(18)------(18)r16-14-----!
--14h16---------------------------------------!
----------------------------------------------!
----------------------------------------------!
 
Note: b - is for bend       
      The brackets are for the note to bend to.
      r - is for return from bend
       - means slide down.
       
Also at the end during the 'G-chord' & lyrics "You will come a little faster
,thanks too ..", this is just a bar in 5/4. The next bar for the chorus is
back to 4/4.
