Peter, Paul And Mary star Peter YARROW is staging a benefit concert in New York in a bid to help find a bone marrow match for an ailing four-year-old boy.

Little Ezra Fineman, who suffers from genetic disorder Hyper IgM syndrome, has been struggling to find a suitable donor so the folk veteran has offered his services to play a fundraising show at which fans can get swabbed and register as bone marrow donors.

Fineman's mum, Robin, says, "It benefits Ezra, but it also benefits any patient looking for a match."

The gig will take place at the Highline Ballroom on 19 May (13).
