Joe, it doesn't make sense that Yarborough would have claimed to have written the song. He was with the Limeliters when THEY introduced the song almost verbatim as Susanne related above, i.e. "...they [the Communist Party in England] wrote a little song about him as if he were dead...".

I'll repeat what I've posted a couple of times elsewhere:
The fact that something appears in an artist's website, on liner notes, or in sheet music for one of "their" songs, does not necessarily mean that the artist wrote it [the blurb, liner notes, etc.] or vouches for its accuracy.
