Chorus: I'm leaving on the new river train, I'm leaving on the new river train, The same old train that brought me here, And it's soon gonna carry me away. O darling, you can't love but one, O darling, you can't love but one, You can't love but one and have any fun, O darling, you can't love but one. Little darling, you can't love two, Little darling, you can't love two, You can't love two and your little heart be true, Little darling, you can't love two. Little darling, you can't love three, Little darling, you can't love three, You can't love three and still love me, Little darling, you can't love three. Little darling, you can't love four, Little darling, you can't love four, You can't love four and love me any more Little darling, you can't love four.
