John Foyster, in his article "Scraps from an Album", writes about the Australian SF scene the 60s and 70s, in Mimosa, " Being a train driver does not bar one from becoming an active fan, as witness the sometimes-remembered-in-Melbourne James Styles - although I feel Roman (Mazurak) was more serious about his work than James was, just as James was more serious about 'active fandom' than Roman was. As Roman pointed out to me at the Worldcon, an old train driver (though he isn't that old) still has to work his shifts, and for Roman that meant he could only attend parts of the Worldcon."
