The melody of I Just Don’t Have The Heart by Cliff Richard runs 304 notes across 46 bars, 2:24 long in D at 125 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 Just Don’t Have The Heart chords and lyrics.
