The melody of Just Walking In The Rain by Johnnie Ray runs 182 notes across 33 bars, 2:18 long in G at 120 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.
