Hey, what's that out there in the park?
Well, I'll tell you what that is, I think it's this:

In the park, nearly dark, what do I now hear, hark hark.
Is it really leprechauns, and have they come back to rock 'n' roll?
Yes, it's them there on the lawn, it's been so long since they've been gone
But Mother Nature's leprechauns have come back to rock 'n' roll.
A-dadda-dum-da-da-da-da-da-la-da
Hum-da-da-da-da-da-da-da-la
Hum-da-da-da-da-da-la
They've come back to rock 'n' roll.
A-dadda-dum-da-da-da-da-da-la-da
Hum-da-da-da-da-da-da-da-la
Hum-da-da-da-da-da-la
They've come back to rock 'n' roll.
See them rockin' and a-rollin', they're wobblin' and a-wiggling'
And they're fumblin' and a-gigglin', well they're here to rock 'n' roll.

Well, they're a-rockin' and a-rollin', and they're wobblin' and a wigglin'
Well, they're rockin' and a-gigglin', oh they're here to rock 'n' roll.
Well, they're sort of (?)
They're plain to see and they're hard to hit.
Well, they don't act now like they used to be(?)
And they done come back to rock 'n' roll.
Well, how they doin' and how they been?
Glad to see them all back again
Well, they're Mother Nature's leprekins, and they done come back to rock 'n' roll.
Hum-dadda-dum-da-da-da-da-da-la-da
Hum-da-da-da-da-da-da-da-la
Hum-da-da-da-da-da-la
They've come back to rock 'n' roll.
Hum-dadda-dum-da-da-da-da-da-la-da
Hum-da-da-da-da-da-da-da-la
Hum-da-da-da-da-da-la
They've come back to rock 'n' roll.
