Not that I'm aware of. It was back during the whole Live Aid/Farm Aid craze. If there is an annual event like that, I don't know of it, and it's undoubtedly much smaller than the Comic Relief from the 80's. I know some comics (Denis Leary, for example) put on benefit shows for smaller, more specific causes like firefighters relief and things of that nature.
What was Farm Aid?? I've honestly never heard of Farm Aid...whereas Live Aid, everyone's heard of Live Aid...I'm pretty sure my mum's got a video of it somewhere...

My bad, Comic Relief is every two years, not every year...
