The last three lines of the bridge of "Bless the Wings (That Bring You Back)" are "The dust of many centuries / Has blown across this land / But love will not be scattered like the sand," which are fairly similar to the bridge of "Lovely to See You" from On the Threshold of a Dream: "Tell us what you've seen in faraway forgotten lands / Where empires have turned back to sand." There are a number of similarities here: both songs were written by Justin Hayward; both of these sections are bridges; and both rhyme "land(s)" with "sand."
Like I mentioned already with "Lovely to See You," this image of the eroding sands of time might have come from Percy Bysshe Shelley's "Ozymandias."
