re: Johnny Cash or Hank?

I haven't looked at it really closely, but I think a lot of Cash's stuff was written by other people, some stolen, some just openly covered.

I'm not sold on him being as genuine of a bad arse as his legend says.

That said, we know Zeppelin thieved their way to fame -- but it's undeniable that they were rockstars and played the stage, like Johnny.

So it's one half and a dozen. I just like to be aware of that kind of stuff.
