Here's an interview with Stephen Jones but it focuses mainly on his horror fiction / editing career.

It does state that he fell in love with horror in the 1960s and has been writing about it since the early 1970s
I'm pretty sure I saw his byline in Hammer House of Horror magazine and early editions of Starburst.
I remember he once told an anecdote about when he was told to '**** off' (or similar) by Riccardo Freda at a film festival so he has been around quite a while.
