After a fire at London's Grenfell Tower left an estimated 79 people dead June 14, a number of musicians teamed up to cover Simon & Garfunkel's "Bridge Over Troubled Water" to benefit those affected by the tragedy.
It was released one week after the fire in west London on Wednesday and had the biggest sales of any single this decade on its first day, selling 120,000 copies, the Official Charts Company said in a statement.
