== Variations in lyrics == 

 There can be many versions of the lyrics of any song, especially of old/classic/folk songs. This is due to varying interpretations by historians, arrangers, and artists. Also, very often verses are left out because of the limitations of recording length, etc. The bottom line is that there are usually no "standard" lyrics.  

 It would be good if somebody found a reliable source that covers these points. Then we could reference it here and on other song pages that feature non-uniform lyrics.
