"Celtic Sonant"

"Celtic Sonant" contains the phrase "yesterday's dreams" ("cups overflowing / Brimful of mem'ries and yesterday's dreams"), which also appears in "Another Morning" on Days of Future Passed ("Yesterday's dreams are tomorrow's sighs").  That the phrase is in both songs might be just a coincidence, but the reflective mood in "Celtic Sonant" ("brimful of mem'ries") seems to hint at an intentional re-use, especially since both songs were written by Ray Thomas.
