It is far from a "cultural thing." Things like bands, especially of international fame, or sports stars are referred to pretty universally. If I say "Iron," few people, if any, are going to assume I am talking about "Iron Maiden." If I say, "Maiden" anybody with a tad of metal knowledge will know I am talking about Iron Maiden. If I talk about soccer and I say "David," well, how many Davids play soccer? Many. If I say "Bekham"... there is only one, so far any way.
Judas Priest does seem to be quite the exception.
