Tony Bennett's signature song (first recorded by him in 1962) is "I Left My Heart in San Francisco." The song is by Douglass Cross (words) and George Cory (music). The damning lyrics are these:
I've been terribly alone and forgotten in Manhattan
I'm going home to my city by the Bay
I left my heart in San Francisco...
12 January 1954, Sheboygan (WI) Press, pg. 6, col. 6:
She (Claramae Turner - ed.) did the "Habanera" from "Carmen," a role that has won her plaudits, doing half in French as she originally learned it, and half in Carmen Jones manner, a clever ditty, "The Green Dog," and then a premiere of a song, "I Left My Heart In San Francisco," written especially for her by Cross and Corry.
Official: "San Francisco"
