The melody of Only You (And You Alone) by The Platters runs 150 notes across 45 bars, 3:01 long in Db at 81 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.
