If you were to type (for example) my youngest son in the "Digitrad and Forum Search" box on the main Forum page, two of the results you would get would be  Post Lyrics 'My Youngest Son'  and  My youngest son came home today.  The latter has Eric Bogle's original version; the former is later, slightly modified.  Don't forget that there are a great many songs in the Forum that haven't yet made it into the DT proper; often if you don't find a song in the database, a little searching will turn it up in a past discussion.
