Hi, Miley. There is a little mistake in the text(first and second line).

.The correct ones are:

"Santa Lucia, per tutti quelli che hanno / gli occhi e un cuore che non basta agli occhi"
("gli occhi" is not repeated)

Hi! I really like this translation!

I think a part of the last verse is missing. It should read as follows (with an apostrophe after "fa"):

fa' che gli sia dolce anche la pioggia delle scarpe,
anche la solitudine.

I also believe (but it's De Gregori, so there's some guesswork involved) that this verse is a plea or a prayer, something like:

Let even the rain in his shoes be sweet
even the loneliness
