To the tune of Camptown Ladies:

The letter N streetcar sings this song - Judah, Judah
Hauling passengers all day long, oh Judah day.

Going to run all night, going to run all day
I merge with the Haight bus late at night
But I'm on my own all day.

BTW, this streetcar line runs near Clayton St (Faith Petric's house, the meeting place of the SF Folk Club for many years), emerging from a tunnel across from the Owl & Monkey Cafe at Cole & Carl, which was a popular spot for folk musicians, as well as to the location of the SF contra dance. It was also the primary line near several of Ed's residences in SF, including Henry St. So I'm sure Ed rode the N line many times.
