Don Leddy featured in Longfellow School program 1933?

"Longfellow School Has Fine Program:  Arbor Day Affair Much Enjoyed Last Week."  I have a clipping but no information about the date or publication.  Longfellow School is still in Pasadena.  "The children ...all assembled on the north side of the school grounds where David Davis dedicated a eucalyptus tree.  Donald Leddy turned the soil with a shining new spade, after which the classes sang "God Gave to Us the Friendly Tree."  Following this, the 3A children circled the tree, each throwing some soil on the roots.  The program was then concluded by singing the Longfellow School song."
