Bob Dylan Fans I need your suggestions.

My dad is a big Bob Dylan fan and this year he wants us all to dress up as characters from Bob Dylan songs for hos birthday party, there are so many It's hard to choose Isis is taken apparently so I can't dress as her. It needs to be character it's easy to make a costume for and is quite obvious because people have to guess who we are apparently, oh what fun it will be NOT.

Being his only child I can't turn up without a costume so any suggestions would be greatly appreciated, please post them in comments.
