Hoping that the internet wisdom can help here. The traditional Derek Broadbent arrangement of The Floral Dance is credited to Katie Moss with a copyright date of 1911. Further research into this is that Katie Moss is credited with the music and lyrics for said song and that she passed away in 1947 - which would by my understanding mean that the tune is still in copyright and that any other arrangements would need appropriate copyright clearance. However, the tune is based upon an old cornish air. My question is twofold - does anyone know where this old cornish air can be found, and would an arrangement of the tune fall foul of copyright law.
