Self-professed 'sex addict and ex-junkie' comedian Russell Brand is fronting this Comic Relief event, which aims to raise funds in order to help those struggling with substance abuse. There's a cracking line-up of music and comedy to boot, with Pusscat Dolls frontwoman Scherzinger performing alongside some of Blighty's hugest seeling acts. No doubt Jessie J will impress with her incredible set of lungs, while cheeky chappy lads Rizzle Kicks give hip hop a playful edge. Young singer-songwriter Jake Bugg provides a refreshing take on retro-tinged tracks. Oh, and don't forget the great line-up of comedians, including Simon Amstell, Jimmy Carr, Noel Fielding, Eddie Izzard and loads more.
