It sounds a lot like the sound they were getting around the time of Ballad of John and Yoko/Old Brown Shoe. The mix, the drum sounds, etc are all very similar - fat snare, lots of room sound, guitar a little snarly, and pianos have a narrow honky tonk vibe. I really like the bass tone on there as it is fat and defined. The Badfinger/Iveys stuff is kind of the same sound around that time. I don't remember who mixed/produced it, but it has a McCartney sound.
