We sang about Sally Brown in primary school, merlot. I expect that's definitely off the programme these days!
The other one I recall was a lengthy saga about William Taylor, a bright lad who was about to be married to "a lady fair" but he got press-ganged and hauled off to the navy.
When she heard what had happened, the lady fair - an enterprising lass - disguised herself as a young man and joined the navy. She spent the next several years sailing the world and looking for William or news of his whereabouts.
Eventually, she found him, settled somewhere in the Caribbean I think and married to another woman. By the time he'd served his time in the navy, William thought the lady fair would have got tired of waiting for him and found herself a new love.
So far as I remember, it all ended in tragedy. The lady fair stabbed and killed poor William and then herself.
There were loads of 4-line verses of this tosh, about 15 I think and when I was 9 or 10 we had to learn all of them and sing them beautifully at a schools music festival. It was awful - could have put us all off music for life!
