Edited sentence: I believe that what the lyrics mean is that.In my opinion this song is not about anybody leaving a band at all.In my opinion this the intent of this song is to mock Christianity and it has nothing.In the line " Theres no sign of the morning coming" is to say Where is this savior where is he.Jesus Christ has not returned to earth as promised and us Christians are left alone here "like a Rainbow in the Dark".So keep watch he will return.The state of society today is just as Jesus said it would be.This is of course my opinion.To me "You have been left on your own like a Rainbow in the Dark" is saying that there is no God where is this Jesus.promise@tts.that is supposed to return to earth.to Earth as he promised.to do with anybody leaving any band
