I do remember "South Street" well PLaw. As a matter of fact, when I saw you first mentioned it, the music trivia buff in me came out, and I was going nuts trying to think of the artist. I wouldn't have guessed it, but now that I know, it does ring a bell. :p The thing is that song was just before the "hippie" era, if I recall. I assume they were referring still to what? Hipster, beatnik?????? I had no idea that South Street was in Philly though.
As far as the attractions go, I'm up for seeing where all the "hippies" meet and if we are in the area, I'd like to see the "Rocky" steps. If not, that's ok too.
