The song I am after, 'the old ways of the traveller are dyin'. I heard it once

Could the song that you are after be the one that starts:-

The old ways are changing you cannot deny
The day of the traveler's over
There's nowhere to gang and there's nowhere to bide
So farewell to the life of the rover.

in which case it is Ewan MacColl's Thirty Foot Trailer which is available on this site at
