Whoever tried to rhyme warrior and bore ya should have that line changed by everybody.

It certainly wouldn't rhyme where I live - but I have often heard Americans pronounce "warrior" in a way that makes that a perfect rhyme.

Of course it's as well to remember that a lot of songs were collected from people trying to remember and reconstruct songs they hadn't sung in a long while and maybe weren't too sure of all the words in the first place. If a version of a song looks like it's got the odd mondegreen, there's nothing disrespectful to the tradition in trying to correct that.
