Neil Young has been quite vocal about his distaste for Donald Trump, and during his performance at the second night of the Desert Trip festival last night, as Billboard reports, he made his opinions known with some good ol’ fashioned political humor.

In a reference to tonight’s Desert Trip headliner Roger Waters and Pink Floyd’s The Wall, Young joked to the audience, “Come back tomorrow night — Roger is gonna build a wall and make Mexico great again.” Afterwards, he launched into “Welfare Mothers,” his 1979 song with the chorus “Welfare mothers make better lovers,” and joked, “That’s Donald Trump’s new campaign song. ‘Welfare Mothers.’ You heard it here first, folks.”

In true Neil Young fashion, he also tweaked the lyrics of “Rockin’ In the Free World” and “After The Gold Rush” to reflect current environmental concerns. Later in the evening, he performed with Paul McCartney.
