the first time I herd the song redwing I was at the royal institute of music of the 20 and the first recording of this song was a 1908 recording by len spencer and henry burr. I was there with my mum and dad and not to forget my sister clare but I was unaware that other songs are sung to the same tune which are called when the moon shines tonight on charly chaplin and union maid which I have never herd before. if you are wanting this tune and wanting to write newer words I could help you with the tune. thank you from joe.
