Anthony and James both started out in British league racing before moving to the US. Ironically, both moved to the St. Louis area where I was based! I used to hang out with James regularly, but then he got into the family thing and I moved to Cincinnati...
Of course Britain is responsible for its own demise, and I think it is just not attractive enough for Americans now. Of course, there isn't the quality of American speedway now, but that could be related to the lack of incentive both here in the US, and in Britain.
