The event on March 23 at Windmill Brixton will see musician Kayleigh Cheer drum for 12 hours straight.
Cheer is helping to raise money for Eden Veremu, from Brixton, who suffers from Myoclonus Diaphragmatic Flutter (MDF), an extremely rare disease in which sufferers experience uncontrollable muscle contractions, seizure and migraines..
Last month Trudi Veremu, Eden’s mother, launched a Gofundme campaign to raise £6,000 so they can travel to Colorado Children’s Hospital in the US for specialist treatment.
So far they have raised just over half the amount needed but cannot yet pay for the full treatment.
Veremu said the donations so far from “our wonderful community have just overwhelmed us”.
