OK, somebody's gonna point out it's in the DT--but I didn't manage to find it!
Just wondering if anyone knows this song.
there are variations in spelling of the surname.

I have a bold companion, John Riley is his name
In fair or stormy weather boys, John Riley’s always the same
His heart is like a mountain and his honour you cannot buy
And whenever it comes to drinking time,
your honour, John Riley is dry!
CHORUS:
Buys his ale, by the pale, he’ll order Susana to go out and buy Dublin Stout,
then he’ll shout Drink whiskey and never say die
Rye whiskey rye, gin and lime, he’ll knock back a double and then he will shout,
Maryanne, fill your can, for your honour John Riley is dry.
