This is probably common knowledge however, here we go.

Paul Simon asked Linda Ronstadt what were her earliest childhood memories. She replied she remembered lying in her crib in Tuscon, Arizona and hearing the Mission bells ringing.
Hence ....

      
       In early memory
       Mission music
       Was ringing 'round my nursery door
       I said take this child, Lord
       From Tucson, Arizona
       Give her the wings to fly through harmony
       And she won't bother you no more

(From "Under African Skies")
