 after the intro riff 1 is played 16 times and
 then riff 2 is played until near the and of the
 song when there's a rest for one bar and then
 riff 2 again 4 more times, listen to the record,
 it's not difficult. Having said that riff 1 IS 
difficult,
 I can't play it without some of the strings 
ringing,
 mainly the E and A strings. I can damp down A by 
putting
 my little finger on it but E still rings. Any 
suggestions?
 I'm not sure about the intro, he plays it too 
fast for
 me to hear, but that sounds about right. (-5___-) 
means sustain 5.
 Thanks, Nick
