He’s never far away from the latest charitable cause.

So it’s perhaps unsurprising that Bono found himself the VIP guest during Saturday night’s performance of Broadway’s hit show Eclipsed.

The U2 frontman joined the production’s main star, Lupita Nyong’o, as the cast remembered missing schoolgirls abducted in Nigeria.

The veteran rocker, 55, was an audience-member of Danai Gurira’s drama, which is set amidst the Liberian Civil War.

Following the acclaimed show, he joined the stars for the curtain call at Manhattan’s Golden Theatre where they honoured the 219 missing youngsters who were abducted in Chibok two years ago.

‘They were taken from their high school 747 days today,’ Bono said. ‘If they were American or Irish girls, we’d get a daily report,’ he told theatre-goers.

Sadly, there was no mention of the countless boys who’ve also been taken hostage by Boko Harem.

Despite this, Kenyan-Mexican actress Lupita, 33, was equally vocal with the captive audience.

‘In our story, we witness the power,’ she declared after receiving applause for her latest live performance.

Still dressed in character, the Academy Award-winner wore a pair of skinny jeans with a turquoise-coloured T-shirt and a headscarf.

Naturally, Bono stepped out in his trademark look, which consisted of a T-shirt with a denim jacket.

He also sported a pair of rose-coloured glasses and an earring, which the Irish singer/songwriter is rarely seen without.

Following the show, he was later seen partying with the director backstage.

Unsurprisingly, Lupita has scored glowing reviews for her the show, with Adam Feldman from Time Out New York describing her as ‘radiant in this inspiring, urgently powerful tale of endurance.’

Similarly, Charles Isherwood from The New York Times described it as: ‘A riveting, superbly acted production. Lupita Nyong’o’s tremendously accomplished performance cuts to the bone.

‘This moving play flickers with light, humanity and hope.’
