Just found this information; abridged from a strathspey and reel society internet newsletter.

"Bluebell Polka was first found in a Kerrs music collection of "merry melodies" in 1875, without a composer. Around the turn of the century it was published in Kerrs 'new and popular music' with F. Stanley's name as composer. International folk dancers adopted the tune for couples dancing the Irish dance Siense Berte(?)-" excuse the last sentence I don't know what it means. Words were later added to the tune.

Normally I would not give information out without checking primary sources (as I would be the first to complain if misconceptions are spread on the copyright works we own!) However, this could well be a trad. instrumental. But the MCPS, clearly have Stanley as composer and Westminster Music as 100% Uk owners. It partly depends on whether Mr. Stanley shuffled off his mortal coil over 70 years ago, what consitutes a recognisably unique registered arrangment etc. The lyrical arrangment is modern.
