Of course if you don't remember much about the tune it isn't very useful but the next day I played around a bit with tune fragments but found nothing appropriate in the searches. I sometimes get off on the wrong track thinking it is something about Peas so I checked that out, but found nothing that was correct. Gathering Peascods, a very nice tune that I have done English Country Dancing to, has almost the right sounding name but is not it. So I gave up again.
Then a few hours later I remembered. It was Bean Setting. That path in my brain between planting and harvesting finally connected. My recollection of the tune was somewhat off. I did discover that Thelwall Morris has a varient of Bean Setting called Brain Testing which seems appropriate.
