When I was in New York in the summer I did a walking tour of Harlem which pretty much starts at 110th street. I didn't realise the significance when I first heard this song. I loved Harlem.
Tony - I haven't seen the film. Harlem always had a bad press (and still does in some ways) but I love it there. The people are fiercely proud of the place and it much less materialistic than other parts of NY.
