What happens in Just For One Day?
The musical opens in October 1984, with Bob Geldof — frontman of the increasingly unfashionable Boomtown Rats — sitting at home watching Michael Buerk's BBC News report from Korem in northern Ethiopia. The famine footage prompts what becomes the founding instinct of the piece: that something has to be done, immediately, and that as a famous person he might be able to do it.
Band Aid
The first act traces Geldof's collaboration with Midge Ure on the Band Aid single "Do They Know It's Christmas?" — the late-night writing session, the recruitment of every available British pop star (George Michael, Paul Young, Boy George, Sting, Bono, Phil Collins, members of Duran Duran and Spandau Ballet), the SARM West studio session on 25 November 1984, and the song's release a week later. The single went to number one in seventeen countries and raised £8 million for famine relief — at the time, an unprecedented sum from a piece of pop music.
Live Aid
The second act is about the concerts themselves: the eighteen months of planning, the political and logistical near-disasters, the eventual broadcast on 13 July 1985 from Wembley Stadium and JFK Stadium in Philadelphia, watched by an estimated 1.9 billion people across 150 countries. Onstage we see Queen's defining twenty-minute set, Bowie's surrender of his last four minutes to the CBC famine footage that played behind "Drive", U2's career-making "Bad", and Paul McCartney's piano breaking down during "Let It Be". Offstage we see Geldof's mounting exhaustion, the famous expletive on the BBC News broadcast that quadrupled donations within an hour, and the moral and political questions about the entire endeavour that the show is honest enough to leave unresolved.
Aftermath
The final scenes look at the Band Aid Charitable Trust's continuing work, the complications of celebrity humanitarianism that have followed Live Aid into the present, and the personal cost to Geldof — the end of the Boomtown Rats, the public weight of the role he never asked for. The musical does not pretend the questions are easy. It does insist, in its closing moments, that the impulse was right.
