Song to go with these lyrics?

Hi I need a song that would go with these lyrics that is just instrumental. Please help!





Cool it, magma, lava too;


We're gonna make igneous rock from you.


Under, over, through and through 鈥?br>







Just look at the signs and they'll give you a clue.





If you see large crystals from coolin' slow.


Magma's been intrusive down below.


From the batholith to the smaller sill.


Start with granite, keep goin' down.








Cool it, magma, lava too;


We're gonna make igneous rock from you.


Under, over, through and through 鈥?br>

Just look at the signs and they'll give you a clue.








If the crystals are small or not even there,


Lava's been coolin' quickly up in the air.


Extrusive volcano, lava plains and plateaus


Basalt and pumice are all around.








Cool it, magma, lava too;


We're gonna make igneous rock from you.
