Who of the Four Seasons sings "December 1963 (Oh What A Night)"?

Question

I know The Four Seasons sings this song. I remember in the musical Jersey Boys, the character Bob Gaudio sings it.

Well, In the music video I saw now:

the drummer was singing the main part. It's not Franki Valli (who does that first refrain type passage). I thought Gaudio played the keyboards, so I don't think that's him. Can someone help me identify that main singer?

Answer 1

Valli objected to parts of the melody - so Gaudio redid the words and Parker redid the melody until all were content with the finished product..
