I listened to Keys of the Kingdom yester-day and noticed a couple small things about "Lean on Me (Tonight)," specifically about the lines "The Northern lights / The Southern Cross / I'll give to you."
Because "Northern" and "Southern" describe opposite ends, there's a sense of the range of things that the speaker/singer is willing to give.
"The Northern lights" is sung to the notes G A B A, and "The Southern Cross" to the notes F G A G, so even musically, north is above south.
