When Mary WebB wrote the Nothern LIghts of Old Aberdeen in 1952 the 2 folk songs that she might have heared were There's More Pretty Girls Than 1 a song that Woody Guthrie wrote and sung in the 1940s but the one that is the song that is the idea that Came to her in writing this song was a song called In My Liverpool Home which I think was traditional written back in the 18th century or before. Thank you verry much from what Jim Maclane for the story you sent on meeting up with Mary and all that info from Joe.
