OK, the CD liner for English Country Dances is pretty sparse...

Juice of barley (1690) is a spritely, flowing Irish-sounding tune that was once a popular song. A good dance for beginners. (Longways, 7x through dance and tune.)

I've never heard of Allmusic.com, and it didn't showup in my goggle search.

I had no more information to give. As I said, I googled a lot about the dance... but I was hoping that someone had info about the song.
