Greg isn't gay, Grant is & and no one, including Grant & Bob, has ever come forward and said they were an item. They've said they never tried to cover it nor did they talk much about it. It was an open secret; they just didn't go around talking about it as it had nothing to do with the band. I've read Greg is married, I believe, for his 2nd time to a woman who works with him. The only reference to Husker Du in the resteraunt is a B&W 8x10 live shot on a wall. His wife who is about 20 years younger didn't know for a long time that he was in Husker Du as she wasn't that familiar with them.
The Warner albums do sound brittle. I bet Mould was pushing to be the loudest in the mix but his hearing was probably shot by then. I think he has tenitus.
