The melody of 2000 Decembers Ago by Joy Williams runs 415 notes across 62 bars, 2:58 long in Gm at 90 beats per minute. The tab sits almost entirely in the first two frets, 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.
