I know what you mean! It's really a beautiful song, try this:
1. Sound out the notes one by one with both aligned together.
2. Once you get the orientation right, shift your fingers up and down (C-B-C, A-G#-A) while concentrating on the index finger, try to lock your last finger so it runs smoothly together. Repeat the steps!
3. Do it slowly, you'll get it in time!
