Book excerpt: Switch off the 21st century and take a step back to the 1980s. "Do They Know It's Christmas, Yet?" is a hilarious journey through love, loss, second chances and joyful hope. During a global pandemic, you'd be forgiven for thinking life couldn't become more complicated. Unless you are Tash and Jamie Summers. On Christmas Day 2020, an unfathomable - and entirely accidental - return to October 1984 causes significant collateral damage for these squabbling siblings, and they have conflicting obligations. Hers is to return to her baby son in 2020, his is to get 1984 back on track, because as it stands Bob Geldof won't form Band Aid or release the famine beating song "Do They Know It's Christmas?" Which is kind of a big deal, because the song led to USA For Africa, and Live Aid, the most famous live music event of all time. And it's all their fault. It's a tricky one: try to return home to your baby, or feed a million others? "...such a bloody brilliant story!" "The brilliance of the dialogue shines through" "Deserves to be made for TV!" James Crookes has been writing comedy for TV and Radio for twenty years. He has contributed to shows on BBC One, CBBC and CBeebies, along with producing and co-presenting the Bauer Radio breakfast show, Big John @ Breakfast, since 2004.
