Okay you should notice that the intro solo is an octave lower than the main solo.  This is how Eric Clapton plays it:

   Intro: (repeat 2x)
e:---------------|---------------------|-
B:---------------|---------------------|-
G:---------------|---------------------|-
D:-------3-------|-7-5-3----3-5--0-5-7-|-
A:-0h3h5--h5h3h5-|-5-3-1--5-1-3--0-3-5-|-
E:---------------|--------3------------|-
 
   And here's the solo:
e:----------------------|--------------------|----------------------|-
B:----------------------|--------------------|----------------------|-
G:----------------------|-12-----------------|----------------------|-
D:-------12h15p12----12-|-----15--14------12-|-------12h15p12----12-|-
A:-12h15----------15----|-------------15-----|-12h15----------15----|-
E:----------------------|--------------------|----------------------|-

e:--------------------|-
B:--------------------|-
G:-14--12-------------|-
D:---------14------12-|-
A:-------------15-----|-
E:--------------------|-

Okay, and as for that solo, you play it as many times as in the song.
