Written by Neil Diamond — you know, the guy who wrote “Kentucky Woman” for Deep Purple and “Red Red Wine” for UB40 — the first thing I need to report about “I’m A Believer” was that it kept future Certain Song “Snoopy Vs. The Red Baron” from hitting #1 at the end of 1966, something which young Jim might have been pissed off about had he cared about anything but singing “Snoopy Vs. The Red Baron” over and over and over again.
That’s Diamond on the acoustic rhythm guitar — it’s a good performance, I wonder whatever happened to that dude? — probably his way of making sure that his song-for-hire was in the right hands.
