Song of the Celts is a patriotic song sung by several groups, notably the Wolfe Tones. Since the lyrics of the song discuss unity amongst Irish, Scottish, Welsh, Manx, Breton and Cornish ethnic groups, it may be regarded as an unofficial anthem of the Celtic people. Some sources [1] list the song as "traditional", however a version of the song has been attributed to A. P. Graves by author Miranda Seymour in her biography of his son, poet Robert Graves. [2]
