These days the Canadian singer, 75, is as likely to be belting out protest songs as performing whimsical tunes

With 13 albums, more than 12m sales in North America and a devoted following, he’s been called the most popular children’s singer in the English-speaking world, a title that has spanned generations. But pivoting from hits such as Bananaphone and Baby Beluga, the Canadian singer Raffi Cavoukian has since followed in the footsteps of his folk music heroes, dedicating much of his later career to advocating on children, social justice and the climate crisis.

“Nobody can guarantee a future, but who has the right to steal our children’s future?” the 75-year-old, who performs as Raffi, said in an interview. “The stakes are very high right now. People ask me if I’m hopeful. But I heard recently that hope is a verb. So I’m active.”
