MikeL2 (sorry if I didn't get your ID right) proposed this as a 'modern' traditional song: http://www.youtube.com/watch?v=6E2hYDIFDIU based on the amount of covers it's inspired and how it's now being belted out at every pub Karaoke night on the planet! It's certainly a song that's been inherited by different generations, and will no doubt carry on being sung well into the forseeable future.
