Georgiansilver's link leads to another song now.

We always used to sing Love's Old Sweet Song at Christmas parties.

The one I particularly remember my father singing was his own version of the Minstrel Boy
The minstrel boy to the war has gone
In the ranks of the chef's you'll find him
A tall white hat he has putted on
etc
He was an army cook in the war, had work in an antique shop before but cooked in a hospital for the rest on his working life.
