An anonymous GUEST said, "If I want to call a song traditional, then I will."

That's fine, call it what you will, but don't record it or perform it and credit it to "traditional" if you know it's composer. The composer of a song deserves to be credited for his/her work.

For many years I, quite innocently, used to perform "Where The Wild, Wild Flowers Grow", thinking it was a traditional folk song until I heard Cathy Fink sing it and credit Ola Belle Reed. I now always mention Ola Belle when I perform the song.
