I haven't been through the whole thread so apologies for any repetition, but here's two nice ones I picked up on recently... (no spoilers): In AGOT Dany (iirc - could be another female character) is described as being "with silver bracelets on her wrists" - this is a Dylan lyric, from "Shelter from the Storm". Is GRRM a Dylan fan? I bet he is! Arthur Conan Doyle coined the expression "the Narrow Sea"... to refer to the English Channel.
