In his memoir, One Train Later, Andy Summers described Sting’s demo for "Every Breath You Take" as a “Hammond organ thing that sounded like Billy Preston.”  But Sting told him to make the song his own.  

“It’s a simple chord progression and shouldn’t prove a problem,” he writes.  “The track rolls and I play a sequence of intervals that makes it sound like The Police.  It is clean, succinct, immediately identifiable.  I play it straight through in one take.  There is a brief silence, and then everyone in the control room stands up and cheers.

“With this lick, I realize a dream that I have cherished since first picking up the guitar as a teenager—to at least once in my life make something that would go around the world, create a lick that guitarists everywhere would play.”
