I saw him at British Summer Time 2014, unfortunately because of that performance I can't quite call this a total surprise as he looked like he was ready to drop dead right there on stage.
However, he has my complete and utter respect for being so completely passionate about rock n roll music that he pushed himself to keep performing until the very end. Most people would have retired so that takes some serious heart and soul.
RIP big man, will be jamming some Motorhead in memory of him, Download Festival 2016 won't be the same without him.
