The melody of I Need You by The Beatles runs 115 notes across 27 bars, 1:55 long in A at 100 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.
Prefer to strum and sing it instead? I Need You chords and lyrics.
