Someone is tossing petals in a stream Somewhere someone is standing at the foothills of their dreams Someone got a paintbrush, is painting over doubts Someone opened up his eyes and saw the sun coming out Someone was captive and found the courage to get off From a boulder in the well, somewhere the rain has stopped Someone is finding the place where they belong Everyday is summer somewhere in the world And the summer boys are headed for the falls to kiss the girls With their impatient hands groping honey breasts and curls They are filled with desire And high in the hills there's a baby being born As forgiveness and peace wash over bruises and sores People bridging the distance over nettles and thorns Everyone aboard on the merry-go-round Some things will rise up so that others come down If the devil don't dance, heaven won't shine It's a mighty thick haze and it's a pretty thin line If the facuet is tightened up the love won't flow If the love isn't bright enough the corn won't grow If the night isn't dark enough the moon won't glow A rich man counting money, a tired man counting sheep While the safe man counts his blessings, the hungry man has beans There's a million people praying, raising up their eyes To what turns out to be the same god, the same sky We are slightly scared of death, a little bit afraid So we celebrate everything we can think to celebrate We shall sing out loud to keep the hounds away Everyone aboard on the merry-go-round Some things will rise up so that others come down If the devil don't dance, heaven won't shine It's a mighty thick haze and it's a pretty thin line If the facuet is tightened up the love won't flow If the love isn't bright enough the corn won't grow If the night isn't dark enough the moon won't glow Prisons will crumble and governments will fall It's the order of freedom to be preceded by walls Cause the truth would be worthless if no one ever lied So we carry our shame in the interest of pride And we have all these questions to make us go roam And we've got all this distance to make us come home As the sun burns, a child learns, the tide churns, the world turns Everyone aboard on the merry-go-round Some things will rise up so that others come down If the devil don't dance, heaven won't shine It's a mighty thick haze and it's a pretty thin line If the facuet is tightened up the love won't flow If the love isn't bright enough the corn won't grow If the night isn't dark enough the moon won't glow
