Thanks a million. Believe it or not, with this you have given a whole new song to me.
Maybe I'm exaggerating but what if someone who really understands the words asks me what "hearties" are? I couldn't tell a dictionary that even mentions this word just to prove that it really exists. I love to sing for people who listen to lyrics so I should also be able to explain things if asked - correctly.
In comparison - "iron and chains" vs. "iron chains" is far from worrying me. Much too difficult to even hear the difference.
(P.S. "Servus" is the bavarian expression for "G'day" :-)
