I played him a little bit of the song down the phone line and he gave me his blessing."</p>.<p>The song was released at midnight on Friday, with proceeds going to humanitarian relief.</p>.<p>The song carries special significance for Gilmour, as his daughter-in-law is the Ukrainian-born artist Janina Pedan.</p>.<p>He told the <em>BBC</em> she had inspired the artwork for the single, which contains the national flower of Ukraine, the sunflower.</p>.<p>"My daughter-in-law told us the story of a woman at the beginning of this conflict, giving sunflower seeds to Russian soldiers and saying that she hoped that sunflowers would sprout where they died."</p>.<p>Gilmour said he found the "powerlessness of the West" in the face of Russian aggression "infuriating" but said he supported the ongoing sanctions against the country.</p>.<p>"It's a shame that the people who suffer most are the ordinary people of Russia - but that is the way the sanctions work.
