I don't know, but somehow I always saw "Daniel" as being part of the great gay "brotherhood", which is why the Wilson-Phillips cover that so many people loved sounded so empty to me. Interesting that even though Daniel can't really see, he claims that Spain "is the best place that you've ever seen," even though he apparently has never seen it (literally) himself.

Another possible (and not necessarily incompatible) explanation is that the narrator (like Sir Elton John himself) has a fairly serious vision impairment and feels a brotherhood with the fully-blinded Daniel.
