WHEN SHE’S NOT at her day job in a medical office near Fillmore, singer-songwriter Candace Roberts can often be found on the stage or in a cabaret.

Her recent music video, “Hello Ed Lee” — an adaptation of Adele’s mega-hit “Hello” — is a plaintive cry to the mayor of San Francisco about what she calls “a tale of two cities, and not the book, but reality.” Over images of street tents housing the homeless, she sings: “Oh this city is filthy rich, yet there’s crisis in the streets.”

“Hello Ed Lee” follows Roberts’ 2014 video, “Not My City Anymore,” which strikes a similar theme.
