Yes, they were there. Al Gore, with Tipper to his left, was on the aisle and Karl Rove was behind him. I'm trying to think if he was seated right behind George H.W. Bush, or if there was another row between them. At any rate, I didn't see mugging and when Fox just replayed some of the service and the crowd-scanning shot showed them, their expressions looked engaged and normal. (this in contrast to the extremely bizarre expressions captured several times on the Clinton faces)
There were people between the Gores and Pres Bush #41 -- Gore was back quite a ways if I remember. I didn't know he was there until I saw him much later.
Here we go ... Battle Hymn ...
