Tell us what you've seen in faraway forgotten landsAlthough, appropriate to their being "forgotten," the "lands" is cut off:
Where empires have turned back to sand.
The "empires... turn[ing] back to sand" is the same image as Shelley's once-vast domain that has since "decay[ed]" so that only "lone and level sands" and fragments of a statue remain.
There really isn't anything else in "Lovely to See You" that seems connected to "Ozymandias," but between the same image of "empires... turn[ing] back to sand" and the land(s)/sand rhyme (which is also in "Ozymandias"), I think Shelley's poem might have influenced "Lovely to See You," if only slightly.
