The melody of Two Little Boys by Rolf Harris runs 320 notes across 65 bars, 2:59 long in Gb at 116 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.
Prefer to strum and sing it instead? Two Little Boys chords and lyrics.
