I know of at least one person who was convinced that "The Bakewell Witches" was traditional.......For all I know there may be more! What's also nice is digging an old text out of an archive somewhere, making a tune for it, singing it around and then, years later, watching the resulting song (same words,same tune) turn up on CDs as 100% 'trad.' Even though I'd obviously appreciate a little credit now and again it's good to clap myself on my shoulder and say "Well done!".
