Similarly, 'Dear Mrs Roosevelt' is a song by Woody Guthrie which Dylan sang at the tribute concert after Guthrie's death. '1913 massacre' is another Guthrie composition.
'Fixin' to die' is a Bukka White song.
Jerry Jeff Walker wrote "Mr. Bojangles".
'Cuckoo is a pretty bird' is a traditional folk song, as are 'Froggie went a courtin', 'Gospel Plow', 'Handsome Molly', 'House of the rising sun', 'Jim Jones' etc.
Obviously Dylan's versions of these songs are relevent but he didn't write them and it creates confusion to imply that he did. Perhaps, instead of moving them, the correct attribution could be given on the Dylan site?
