Hi Kath - yes, I'm sure your post was partly in my mind when I made that remark! (I've also been wondering whether these images might be the foundation of an ABBA post at some point.)

I linked to your post at an academic children's lit forum I'm on, by the way, so if any strangers drop by at your place that may be the reason. And look, I've just linked to it again!

Also, have you thought about getting an OpenId, if you don't already? That would allow you to comment unanonymously, I think, should you wish to.
