I'm not sure what Slade is singing on the recording, not having access to it, but this verse usually runs:

Oh, Sally lives on the Old Plantation
Way, hey, roll and go
Oh, she is a member of the WILD GOOSE Nation
Spend me money on Sally Brown.

However, Hugill says on p.130 that "U.S. Nation" is a legitimate alternative.

Hugill also notes, on p. 132, that Stanley Slade always sang the lines below as:

She drinks rum and ALWAYS chAws tERBACKER

Her eyes are black and her lovely hair is curly

Cheerily,
Charley Noble
