The melody of December 1963 by Frankie Valli & The Four Seasons runs 280 notes across 49 bars, 3:05 long in C at 100 beats per minute. The tab sits low on the neck, mostly under the fourth fret, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
