The title track of The Vaccines' Melody Calling EP was penned by frontman Justin Young during Christmas 2012. He told NME: "I'd built loads of vocal stuff around the main chorus vocal, and then ended up muting the main part so all that's left is the harmonies – that's why they're all falsetto. It moves in a different way. It's not one you bang your head to; maybe you sway a bit more."
The song's music video finds bassist Arni Arnason plucking up the courage to call a woman on the phone. It was shot on East London's Regents Canal and in the London Fields outdoor swimming pool.
George Harrison's 1971 song "Bangla Desh" was the first major charity single. It was part of a concert held to bring relief to the people of Bangladesh, who were fighting for independence and suffering from a famine.
