What'll I Do

"What'll I Do" is one of the few songs by Berlin that is clearly biographical. His fiancée, a society beauty named Ellin MacKay, had been sent to Europe by her disapproving father, a very wealthy Long Island magnate, in the hopes that MacKay would forget Berlin. (She did not and eventually they married.) The song was written during McKay's "tour" of Europe. In the lyrics, the singer longs disconsolately for his love, imagining how he can go on without her.
