EDIT: Apparently Rat Salad was the other riff that I recognized during the drum solo and Sabbath Bloody Sabbath was the riff before Paranoid. I don't know how I missed that one. And for some reason on setlist.fm after Under the Sun a song called Every Day Comes and Goes is listed. I don't know what that is. I actually thought they cut that song short rather than added another segment.
