Terry Griffiths: 40 years at the Crucible
Former world champion Terry Griffiths runs down his top memories from four decades at the Crucible.
Snooker's World Championships were first held at the Sheffield theatre in 1977. Welshman Griffiths won the title in his first appearance two years later.
He tells BBC Wales Sport why it's such a special venue and why he hopes we'll see a Welsh world snooker champion again soon.
