Sad news, never really watched their shows a lot, but literally bumped into the pair of them on the prom during TT a few years back, they seemed right enough.

Bit of a shocker. Was only watching them this week and so pleased he looked well. They were promoting the island's queenies. A bit poignant for me. I was diagnosed about the same time, and I found out about Dave today after just after having had my 2 year surveillance scan. If only he had made it to his. RIP.

I met him in the paddock, I think it was 2017. He was chatting to all the fans and people were getting autographs and selfies.
He was outside Guy Martins stand waiting for an autograph. Don't think he got one somehow!

Yes sad news he came across as a really nice chap as does Si King i saw him on the ferry one year going over a big TT supporter. RIP Dave

A real loss, he seemed a good lad. His mate Si will be lost without him.
