It's Diki and a guitarist (OK, that's a band) but it's still canned drums and bass. The recording was made live, so maybe the feel is more alive too. Certainly not taking anything away from Diki's excellent post, but Diki was using a self-made SMF for bass and drums, which is definitely arranger play. Many arranger players do that very often, record the necessary backing tracks in advance, leaving the keyboard free for more uses. Again, not knocking just clarifying.
