Johnston wrote many classic Doobie Brothers songs, including "China Grove
" and "Long Train Runnin'." This, however, was the only time he produced a guitar lick that he knew would become a hit. Says Johnston: "I was sitting in my bedroom in San Jose. I was doing what I always do, I had been up playing guitar for hours. It was like 2 or 3 in the morning. I had the opening riff to it, and I think I figured out all of the chord changes as well. I called Teddy (producer Ted Templeman), woke him up, and played it for him over the phone, and he was less than enthusiastic. (laughing) I think it was because I woke him up. But he said, 'Well, yeah, it might be pretty good. Needs a couple of changes.' But we didn't ever change anything. It stayed the way it was, the way I had it. The chord changes and everything we made are the same. In the studio, the bass part was added by Tiran (Porter), drums were added by Mike (Hossack), and Pat (Simmons) came up with a couple of parts and put in that banjo at the end. And it was the second time anybody had ever used something like phasing on a record. First time was 'The Big Hurt' by Toni Fisher. But things like 'Long Train Runnin',' I said, 'You're nuts. It'll never be a single.' And it was."
