By: Alan Morgan

Rock Cycle Rock

By:Words and Music by Chris Rawlings
(c)Cooking Fat Music, 1995

I've been pounded ground down and smashed all around
in the cycle....rock cycle
I've been thrown up and blown up to the ozone
in the cycle..rock cycle
I've been eroded, corroded and motherloaded
Melted and pelted and ore smelted
I've been chipped and dipped and stripped and skipped
in the cycle...rock cycle
