A beautiful Scottish air 'The Flowers of the Forest'
An Irish 20th Century Song: The Fields of Athenry
The Spin-Doctors 'Two Princes'
My favourite Hothouse Flowers song is 'Don't Go', which was played during an intermission in the Eurovision Song Contest. It has a great video!
Which leads me on to flowers:
Poppies of Flanders Field
Lilies of the Field
