Green wrote: “I said to myself that day I wanted to sell it out, and as you did, have the crowd up in arms from the front row all the way to the back of the upper circle.
“Later that year I signed to virgin and began my journey towards doing so.
“We crossed paths a few times and you always said hello, even when you didn’t have a scooby who I was.
“Your music, your presence, your attitude. It all had such an influence on me. Saddened doesn’t even cut it, and that’s just from me as a fan. We as fans lost a hero today, but my heart goes out to those who’ve lost a member of their family, who’ve lost a friend. RIP Keith Flint.”
