Just wondering because I have a Black Sabbath Tab Book for the album Paranoid (published in 1970 by Hal Leonard) and most of the tabs are different (some only slightly) and (imo) sound better than those already posted.

Better to have 1 correct version of Iron Man than 20 'almosts'

Don't mind posting them if there's no copyright issues or anything.

Yes there are issues. You will find tabs that have been taken from books but it shouldn't really be done. If you did submit an 'Iron man' it probably wouldn't be accepted anyway because there is already a large amount of tabs for the song.

Why do we feel it's necessary to yak about bullsh*t in order to be comfortable?

That's when you know you found somebody special. When you can just shut the f*ck up for a minute, and comfortably share silence.
