“Treasure” lyrics:

“Let’s leave to a far place
It calls to us, that treasure
Hurry, let’s leave, let’s go find it
Oh every day, every night

We would be savage ay ay
We’re savage ay ay
Engraving it on the earth”

“Pirate King” lyrics:

“Raise the anchor, put away your dark hearts
Wherever it is, we can go
We can be whatever we want, just follow us
Raise your hands up high
You and me, under these burning lights, to the bright place
Step 1,2,3 and 1,2,3 Let’s go
Will you be my friend?”
