Be My Baby has no musical resonance I can see with Don’t Worry.
At any rate. by its essence, I meant both songs were founded and on dark events. The original version of Endless Sleep even had the girl drown!
I see what Brian is talking about and I see it. It’s in the harmonies and quite obvious. I write songs. Occasionally I will know where the essence, mood or groove of a certain passage came from (in my mind). If I mentioned to someone and they listened to the two songs they might not even see a resemblance. But I know where the essence of the passage came from.
