I awoke around one o'clock (I don't sleep so well these days) with the melody of "Down by the Salley Gardens" running through my mind.  Although I am familiar with the poem, for some reason I had substituted "Carrie River" for Salley Gardens, and I had to get out of bed, plug in the modem and check on it online.

"She bid me take life easy, as the grass grows on the weirs ..."

Yes, that's good advice. And it's a good simile - grass growing on a weir is in a precarious position, any time the river might rise and wash it off.

There are several versions on YouTube.  Many, actually; but they almost all spoil the song by adding piano accompaniment or other extra stuff.  I like it just plain, voice only, no frills, in its simplest pentatonic form.  So I felt compelled to sing it myself - quietly, so as not to wake Rose or the neighbours.  Claude was still awake, I think, he's a night bird.

Irish music has a haunting quality, especially when the pentatonic scale is used.
