My father has enlisted my help finding lyrics (and a title) to a very obscure drinking song from Yorkshire, England where my mother is from. It was sung in several pubs in Grassington (The Black Horse, Devonshire Arms and Forester's) and one in Cracoe (The Fountain Inn) by her father (my grandfather) Harry Wilson about 50 or 60 years ago... no exact date known
I have no idea what the name is... and very few of the lyrics.
The lyrics I DO have are:

There once was a little mouse fell into a barrel of ale
whilst swimming in that liquor his strength began to fail

Does anyone know anything about this song? I'm not expecting miracles... but i'm kinda hoping for one.:)
