The melody of Poor Little Fool by Ricky Nelson runs 123 notes across 21 bars, 1:07 long in C at 140 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.
