I learned this tune from Helicon’s recording Horizon. It’s a Swedish polska so I uploaded it as a mazurka for proximity. It seems to also be known by the name "Yet another soldier’s joy":
N:Yet Another Soldier’s Joy
C:e. Anders Andersson
Could this be the origin of the famous "soldier’s joy"?
I’ve noticed the similarities between this Swedish polska and the famous hornpipe https://thesession.org/tunes/1356. Does anyone have any clues?
