Iron Maiden - Wasted Years Tabs

I have searched for 1/2 a year for a tab for the solo of wasted years.I have given up
so i had a shot at making my own tab.I couldn't tab the part when the singing comes back
in. This is my first tab of a solo so there are probably lots of mistakes.
If you have any comments,questions or corrections mail them to me.
If you find a tab of wasted years solo please mail me and give me the 
address so i can check it out.If you know the singing part also mail me.
