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

1956
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.
