I'm sorry but I really need to interject here.
Maeve's "She Walked Through The Fair" is a different situation, because the singer (Maeve) is "telling" about a woman walking through a Renaissance era Faire and sharing with others her news that she is going to be married to a certain young (?) man soon.
The song itself is actually about a man reflecting upon the time spent with his deceased love. One verse is cut from the Celtic Woman version which actually spoke of her passing. The entirety of the first two verses of the Celtic Woman version are the man describing his time spent with his love while their third verse is the man being visited by the ghost (for want of a better description) of his deceased love.
This song never bothered me, neither did My Lagan Love nor Carolina Rua even (we forgot about that one) because the words of the song are not important. It doesn't matter which pronoun is used to describe whoever is being described in the songs. All that matters, or, at least, all that should matter, is whether or not the emotion of the song is there. If a singer can properly convey the emotions felt, then what should it matter if Lynn, Meav, and Lisa use female pronouns.
Now, on that note, I do attest that some people might be bothered by Lisa Lambe's version of Black is the Colour because of the way she performs it. But the thing is, it is simply her interpretaion of the song. Yes, she does perform it in a sensual and suggestive manner, and yes, I realize that bothers some people whenever an artist performs in that manner. But I also think we shouldn't be critical of Lisa's performance simply because of our own insecurities brought about in this era of constant political correctness. Just because a female singer performs a song using female pronouns doesn't make the song and the performance any less aestheitcally appealing.
