One More Bit on Brooks

I have known this Boy before
I have known this Boy before, who
ornaments my alley.
I never saw his face at all.  (16-19)

Is anyone else getting "Prufrock" here?  ("For I have known them all already, known them all" [49].)  I kept thinking I heard echoes, and it got me thinking of the alley that Prufrock first wanders--the poverty-stricken place which he can't seem to explain to the drawing room crowd.  I started wondering if this speaker is an emissary from that fog- and silence-shrouded place: the alley.
