The man that gave Rockefeller Center it's tree this year, called it a "Miracle". It was planted in 1931 by his parents after they used it for a Christmas tree when they were younger. And his mother always said that it would someday be displayed in Rockefeller Center for the Christmas tree. The tree for this year is a Norway Spruce.
The original tree placed in Rockefeller Center was placed by workers building the center in 1931. Officially they didn't light a tree until 1933. The year 1931 had to be a coincidence for the first one and the one displayed this year.
I have never seen any of the trees in the center myself, but it has to be beautiful.
Have a happy and safe weekend.
