Something Malus domestica

I’ll be with you in apple blossom time
I’ll be with you to change your name to mine
One day in May, I’ll come and say
Happy the bride that the sun shines on today
What a wonderful wedding there will be
What a wonderful day for you and me
Church bells will chime
You will be mine
In apple blossom time

I am aware that this is still April not May, but I’m not the apple tree. It hasn’t got a calendar.
