Dave Grohl says old footage he sees of Nirvana bandmate Kurt Cobain on the internet leaves him feeling heartbroken.

The Foo Fighters frontman was talking about when he stumbled across home videos of Cobain on Youtube and it immediately struck an emotion chord.

He says: “I watched this thing on YouTube of Kurt's home movies. He's hanging around with his family in a park, sitting by this stream as these little girls run around.

And it broke my heart, because I knew when that was, and I knew that he wasn't necessarily happy at the time... He couldn't fully experience the joy of life."
