Fiona Apple was on hand at the Standing Rock benefit in Los Angeles on Sunday night, where she performed her anti-Trump Christmas song “Trump’s Nuts Roasting On an Open Fire” and concluded the song by shouting an obscenity at President-elect Donald Trump.

The 39-year-old singer performed three songs at Los Angeles’ Fonda Theater Sunday night, one of which was her anti-Trump parody of “The Christmas Song.” The concert was held to benefit the Standing Rock Sioux and local organizations, who won a temporary victory in their battle against the construction of the Dakota Access Pipeline earlier this month.

“Trump’s nuts roasting on an open fire/As he keeps nipping at his foes,” the lyrics for the re-worked song include. “You’ll cry ‘creepy uncle’ every time he arrives/For he keeps clawing at your clothes.”

At the end of the performance, Apple screamed: “Donald Trump, f*ck you!”

The Standing Rock benefit concert also featured performances from TV on the Radio, Sky Ferreira, Devendra Banhart and Kimya Dawson.
