INTERNATIONAL: British rock band Pink Floyd will release a new song on Friday (April 8) to raise money for humanitarian relief in Ukraine, featuring the vocals of a Ukrainian singer who quit an international tour to fight for his country and was wounded.

The single "Hey Hey, Rise Up" - Pink Floyd's first original new music in almost 30 years - was recorded last week and highlights singing by Andriy Khlyvnyuk from Ukrainian band Boombox, which was taken from a social media post.

Pink Floyd guitarist David Gilmour said he learned that Khlyvnyuk - with whom he had previously performed - left a U.S. tour with Boombox and returned to Ukraine to join the Territorial Defence Forces.

Gilmour said he spoke with Khlyvnyuk while he was in a hospital in Kyiv recovering from a mortar shrapnel injury.

The track, which samples Khlyvnyuk singing a World War One protest song, also features Nick Mason, a founding member of Pink Floyd, as well as Gilmour and other musicians.

Pink Floyd posted on their Instagram Page:

"Tonight at midnight, Pink Floyd will release 'Hey Hey Rise Up', in support of the people of Ukraine. It sees David Gilmour and Nick Mason joined by long time Pink Floyd bass player Guy Pratt and Nitin Sawhney on keyboards, all accompanying an extraordinary vocal by Andriy Khlyvnyuk of Ukrainian band Boombox. All proceeds go to Ukrainian Humanitarian Relief. Listen/download at link in bio. The track uses Andriy’s vocals taken from his Instagram post of him in Kyiv’s Sofiyskaya Square singing ‘Oh, The Red Viburnum In The Meadow’, a rousing Ukrainian folk protest song written during the first world war. The title of the Pink Floyd track is taken from the last line of the song which translates as ‘Hey, hey, rise up and rejoice’. The video for ‘Hey Hey Rise Up' was filmed by acclaimed director Mat Whitecross and shot on the same day as the track was recorded, with Andriy singing on the screen while the band played.
