I've just been pointed towards this lovely interview with Galaxie 500 from a 1990 issue of Ptolemaic Terrascope

PT: You're not a very visual group live. You all stand still and look serious.

DW: That's terror. But if you don't feel like jumping, why jump? It's hard to be charming every night.

NY: People used to ask me why don't you smile? Why should I though? There's nothing especially cheerful going on up there!

Read the whole interview from the Terrascope archives.
