 Thank you for your note. In principle, I agree totally with your "the fact that a single person thinks that the structure and prosody of a refrain could accommodate a different set of words does not deserve mention", but it does also depend on the person making the statement. In this particular case, it is a reputable public figure who has made the claim.  

 Wikipedia is not interested in any one Truth but only in what can be reliably sourced. This means that any given article may reflect contradicting viewpoints, provided each is accompanied by a reference, i.e., a reliable source. In this case, it would seem that the claim, however much it may go against the grain, fits that criterion. 

 That said, the place to raise the issue, if only to engage other people who may know about the subject, is the article talk page, which I see that you have since done. Regards,
