You're better off using the "Digitrad and Forum Search", which I'm told generates URLs that will last longer. The point, though, is not that Jenny couldn't find Banks of the (Sweet) Primroses, but that she wasn't looking for that song in the first place, as she said in her original question.
I've given this some thought, and can't at the moment put my finger on any traditional song that includes a basket, banks, primroses and marriage. You can get quite close with a milking pail or with green mossy banks, but those wouldn't fit the bill. Maybe something will pop into my head later on; meanwhile, this will at least keep the thread current.
