You could always introduce "Flower Of Scotland" as being a "Traditional 20th Century Song", which it is.Similarly,one could argue that Christmas Trees have been used tradionally,since Victorian times,which is also true,as is the tradition,again in the 20th century,of singing "HB2U " on someones' birthday----the fact that we KNOW who wrote both HB2U and FOS is entirely irrelevant. As are those who keep going ON AND ON "AD INFITUM" about the subject ---Does it really matter ?? Not to me !!
