I thought there was some big interpretation where July 1st was the day after her dad supposedly died.

0630 = June 30th?
I read that a long time ago here on some AHS discussion. Was that all made up?
Lyrics:
If it's fine tomorrow, I will go to that sea
Changing the pain with the tears shed yesterday
Into tenderness
If it's fine tomorrow, I will go to see you
Yes I will be long with you
Tomorrow, the day after tomorrow
Even if it rains tomorrow
I will go to see you
And give this song to you
If it's fine tomorrow, I will go to that sea
The pain with the tears shed yesterday are changing
Into tenderness
If it's fine tomorrow, I will go to see you
Yes I will be long with you
Tomorrow, the day after tomorrow
