Close. There are two potentially relevant Farnam songs that may have been conflated in this discourse. One is That’s Freedom, which includes the lines "From the mountain to the valley / From the ocean to the alley / From the highway to the river". And the other is Two Strong Hearts, which repeatedly uses the line "Reaching out forever like a river to the sea". Neither quite uses "from the river to the sea", but together they give the same sort of impression.
