[BLACK SABBATH (Iommi/Butler/Osbourne/Ward)]      I feel unhappy   I feel so sad   I lost the best friend   That I ever had      She was my woman   I loved her so   But it's too late now   I've let her go      I'm going through changes   I'm going through changes      We shared the eve's   We shared each day   In love together   We found a way      But soon the world   Had its evil way   My heart was blinded   Love went astray      I'm going through changes   I'm going through changes      It took so long   To realize   That I can still hear   Her last goodbyes      Now all my days   Are filled with tears   Wish I could go back   And change these years      I'm going through changes   I'm going through changes
