"Care of Cell 44"

Years ago, I noted that the piano figure at the beginning of "Care of Cell 44" is later played (in a monophonic way) on bass (first at ~0:15).  Yester-day, I realized that this passing a musical phrase from one instrument to an-other continues and expands upon a similar characteristic in "She's Not There," which I'd also previously noted:  after the first chorus, the bass briefly plays the initial notes of the vocal melody.
