actually i think this song is about ozzy's drug problems. this is the anthem-type song he sings as he's encountering the light at the end of his tunnel. all the things ozzygurly said, about how ozzy says "you could have been a better friend to me" is talking about how the drugs had such a tight grip on him. "here i come but i ain't the same" - this time he's sober. "mama, i'm comin home" though, i think IS referring to sharon, because a new, clean (har har) ozzy is coming to her.
