Dominic in his album “Irish Songs” (1958) writes “The Zoological Gardens I got from Mr Brown who sings it regularly in a public house in Kimmage“

Chorus
A Thundering light is no lark
When Dublin city is in the dark
Would you care to go to the Pheonix Park
And view the zoological gardens

I
Last sunday night I have no dough
so I took the moth (1) up to see the zoo
We saw the lions and the kangaroos
Inside the zoogical gardens
II
We went out there by Castleknock
says the mot to me
“Sure! We’re caught on the lock [lough]” (2)
Then I knew she was one of
the rare old stock (3)
Inside the zoological gardens
III
[Says] the mot to me “‘My dear friend Jack’
Would you like a ride on the elephant’s back (4)
If you dont get out of that
I’ll give ye such a crack (5)”
Inside the zoological gardens
IV
We went out there on our honeymoon
Says the mot to me “If you don’t come soon
I’ll have to get in with the hairy baboon
Inside the zooligical gardens
