"I wonder what it feels like to be poor (bis)

To have the wolf a'knockin at the door(knock, knock, knock)

....

As we sat down to tea, Lord Rothschild said to me,

"I wonder what it feels like to be poor"

These are all the words that my brother remembers of a song he used to sing when young. This probably makes it folk song by dint of age, if nothing else, since he is among the small percentage of the world population who are older than me...

Anyway, it sound like something I would like to learn myself...
