There is certainly a fair amount of sound that is probably clavinet on Easy Come Easy Go. I say probably as it sounds as it's had some sort of effect added to it. So it could be a real clavinet effected slightly, or a synthesiser creating a sound that's nearly clavinet. Easiest to identify right at the beginning. I hear the "clav" at the beginning, along with the synth bass (Chris?
) and a number of guitar parts. There's also a more prominent bit after one of the breakdowns later in the song.
