I was thinking about "Care of Cell 44" before I went to sleep (which is apparently a thing I do a lot), and I realized something interesting about it. I've noted before that Rod Argent frequently employs sequential half-steps in his writing. Usually, these are in the bass parts, but I found an instance in "Care of Cell 44" where he does this across instruments.
During the second part of each verse ("thinking of me while you are far away"), the bass goes from G to F#, but then the key changes (right before "you are far away," which - interestingly - seems to further underscore the distance), and it goes to Bb. But right after the key change, the mellotron part comes in, and it starts on an F. So you still get G to F# to F; it's just not all on the same instrument.
