I recently downloaded the last of the Folk Song a Day podcasts from iTunes, though I didn't realize that at first -- I thought I was a day too early. On iTunes, the last track is listed as #364, Fortune Turns the Wheel, and dated June 23. Track #1 is dated June 24 last year, so it has indeed been one year, and there are no days missing (though there are some bonus tracks).

The problem occurred on May 5 and 6, when both Bonny Bunch of Roses (May 5) and Broomfield Hill (May 6) were called track #316.

If you've been wondering what went wrong, you can now stop wondering.
