Julian Lennon, the son of late Beatles star turned solo artist John Lennon, publicly performed his father’s hit song “Imagine” for the first time last week. He stated that he did so in support of Ukraine.

“As a human and an artist, I felt compelled to respond in the most significant way I could,” Lennon tweeted. “Today, for the first time ever, I publicly performed my Dad’s song, IMAGINE.”

In a video of the performance, Lennon and a guitarist sit in a candle-lit room. As Lennon sings the anti-war anthem, the camera slowly swings around them.

“What’s the point now, after all these years? — I’d always said that the only time I’d consider singing ‘IMAGINE’ would be at the ‘End of the World…'” John Lennon stated.

He claimed that the song embodies “our collective desire for peace worldwide” and transports listeners to a place “where love and togetherness become our reality.”

Noting the millions of people who have fled Ukraine’s violence, Lennon urged world leaders to support refugees worldwide and urged people to “advocate and donate from the heart.”
