Try these:

(G)I am a young fellow that's fond of my (Em)fun,
And (G) Ferlin in (D)Derry is (Em)where I've begun.
All (G) over the country, I've spent all my (Em) cash.
With (G)Kitty and (D) Ginny and (Em)Mary McNash.
My father disowned me for being such a rake.
And for (D)spending my time in such frolicksome ways.
The (G)girls, they are sweet, but I'll have you all (Em) know
That my (G)first love in (D)life is the (Em)pure whiskey, oh!
Riddley-i-di, riddley-i-(D)di-di, riddley-i-(Em) di-day.
