Sue, when S & G's version came out, it was attributed to Paul Simon, it wasn't credited as being traditional, or even traditional, arranged by Carthy, which would have been the proper thing for Paul Simon to do. I don't think Carthy was annoyed that SImon was succesful, just that he didn't attribute it as a traditional song, and within the folk community, it was fairly well known that Carthy was a little peeved. Just a couple of years ago, when Free Reed's Carthy Chronicles came out, somehow they got the two in touch with each other again, and Simon wrote a little tribute note for the booklet, and shortly after that, when Simon was performing in London, he brought Carthy out to sing it together!
