I have found it here, it goes like that:

Young Rackabello to the woods he has gone
Rackabello Rackabello riding all alone

Chorus (after each two lines):
    (To me) Rye raddium rudy ida daddium
    Di dye daddium rudy ida dandy

Rackabello down the wood late yester e'en
Woman in the tall tree Rackabello seen

Woman oh why do you sit up so high
Nobody living can come you a-nigh

There's a wild boar living down in the wood
Cut your throat and he drink your blood

Young Rackabello put his horn to his mouth
Blew it to the north and blew it to the south

Young Rackabello come to the wild boar's den
There he saw the bones of a thousand men

Wild boar struck, he began to run
Thrashing down the tall trees as he come along

Fought four hours on a long summer day
Wild boar struck and he would have run away

Young Rackabello drew the wee penknife
Rackabello Rackabello took away his life

Rackabello riding through his own front door
Up jumped the giant from the wild woods of Tor

Up jumped the giant and Rackabello flew
You killed my little pig it's time for you

Into his rocks the giant then flew
Swore to his soul he would tear him in two

Rackabello Rackabello drew the sword again
Rackabello Rackabello split his head in twain
