I'll go along with 'Ae Fond Kiss', and 'From Clare To Here'. 'Do You think I Do Not Know', written by Henry Lawson. Also, although it isn't a folk song, Paul Simon's 'Slip Sliding Away'.

And Alan says his are 'The Water Lily', sung by Martin Wyndham Read, & 'The Moon Was A-Waning', written by James Hogg, the Ettrick Shepherd.

I'm sure I'll think of some more.
