Apparently there were words to Planxty Irwin (aka Colonel Irwin). An English translation of the first verse:

We will take our way without delay
To see a Noble, brave and gay,
The gallant Colonel near the sea,
Him I mean to treat of;
With mirth and joy he fills his glasses,
Delights to cheer both lads and lasses,
This is John I will answer,
The brave English Irelander.

Cheers, S. in Seattle
