From the BBC Shop website, come the news that something called Hunters of Earth (Destiny of the Doctor 1) will be available in January. This appears to be the little documented Big Finish / Audio Go anniversary tie-up which is believed to be in a Companion Chronicles style.

Shoreditch, London, 1963. The Beatles have beaten John Smith and the Common Men to No. 1 and satellites are being launched in outer space. Back down on Earth, strange goings-on are occurring: The normally placid teenagers of Coal Hill are running riot and a master thief is stealing highly specialised equipment. Schoolgirl Susan Foreman just wants an easy life for herself and her grandfather, the mysterious Doctor. She wants to be liked and accepted by Cedric and all the other pupils at Coal Hill School. But there’s trouble in in the streets and bombsites around Totter’s Lane. The teenagers are becoming dangerous…. Their mission: to hunt down anyone different, or alien…. Susan’s quiet life is about to spiral out of control. Having inadvertently started drawing attention to herself she finds herself drawn into a desperate situation. Suddenly, the chase is on and she and her grandfather are now the hunted—
