I have written 2 songs in first person from a woman's point of view - I do occasionally sing the first of those (Scullery Maid), without feeling funny about it; I even stopped the joking introduction "you'll have to imagine I am not the Greek God you see before you, but...". I have even recorded that song with me singing it.

But I have never sung the second of those songs (The Rain Is Falling), except immediately after I wrote it, trying it out in my local clubs. In recording it I asked for the help of Mary Humphries, who did a wonderful job of it, as indeed did also MGAS who includes it in her repertoire.

The reason I sing the first but not the second is more to do with the fact that the second song is part of a trilogy, and the "theatrical" aspect of telling different parts of the story from different viewpoints is what pushed me to ask for a female voice.

I have no problem "gender crossing" in song generally speaking.
