At least for me!
It seems I'm not the only one with serious problems understanding Bob Marley's pronunciation. Checking my Sitemeter, I found out someone searched at Google for the exact words I wrote in my notebook, "my fear is my only courage". Then, following Google's result, I found a couple of blogs and lyrics sites with the same words.
Was I correct after all? No such hope. Checking the official site there came the confirmation of my mistake. Of several people's mistake. Bugger, not even an original mistake!
Well, never mind. I found another site full of this kind of slips and lots of other short "I used to believe" stories. Good reading when you're feeling dull :)
