What is that song we used to be taught as kids to remember the streets downtown?

There’s no rhyme or reason to those street names, so somebody came up with a jingle to use in learning them. There’s a yellowed card at the Central Library with this unattributed verse pasted on it: “From Main we Spring to Broadway, then over the Hill to Olive. Oh! Wouldn’t it be Grand if we could Hope to pick a Flower at Figueroa.” I have interviewed dozens of Angelenos who heard other renditions from a parent, teacher, or streetcar driver. What is the original, and who wrote it? If you can prove you know who came up with the ditty, I’ll send you a copy of the new Julius Shulman Los Angeles: The Birth of a Modern Metropolis.
