The Outfield - Rainbow's End lyrics

Where is your heart tonight I would be lost without you Walking these streets again Searching to find a grain of sand How can I learn if we pretend Someday I'll find my rainbow's end Who rides this chariot of pleasure Over the ruins of Rome Who waves the flag tonight Who lights the fires of [?] How can I learn if we pretend Someday I'll find my rainbow's end Who'll calm this anger inside Who'll give me comfort after a storm How can I learn if we pretend Someday I'll find my rainbow's end
