This is great thanks folks! I had thought of John Barleycorn also as I know there are some good contemporary versions and as it is a personal favourite anyway. I will definitely look in to some different versions of bedlam boys and raggle taggle gypsy and The gallows pole. I like the idea of there being a Led Zeppelin version. Really interesting about an Armenian auld lang syne. I probably wouldn't use auld lang syne as the main song to work on but its a great suggestion as a song to refer to as its timely for the season and is also a song people would recognise which is always great for peoples confidence.
