i though the notes where G D C C  but i might be wrong, i`ll have to try the
ones below but i though i was dead on with the riffs.
i just started learning scales and it sounds like if its played in this
scale paterne which i think translates to g scales?
||----|-*-|-*-|---|-*-|-----------------------------------------
||----|---|-*-|---|-*-|---------------------------------------
||----|-*-|---|-*-|-*-|----------------------------------------
||----|-*-|---|-*-|-*-|----------------------------------------
||----|-*-|-*-|---|-*-|------------------------------------------
||----|---|-*-|---|-*-|------------------------------------------
      1   2   3   4   5

so i just fool around in this scale patern (following the pattern down) and
you can play with the solo.
