"Bell Cow" is an American reel in A major.
I got this from John Lamancusa's website and book. He may have picked it up at the jams at Gettysburg. His note says "as played by Annie Williams".
This is not the same as any of the multiple versions of the tunes known as "The Old Bell Cow".
It is printed in Lamancusa's The Gettysburg Collection of Old-Time Fiddle Tunes (2021).
