Which singers don't look at the audience?

Herbert's first interview cracks me up. I never realized Perry didn't look at the crowd till I read that, then started thinking about the Escape show and realized he was right. JSS also doesn't really look at the crowd either. (I just saw him Sat night, but I noticed that a long time ago as this was the 3rd solo show I'd seen him do) This is not a complaint about voices...What other big name singers don't look at the crowd? We have a local band that plays the same club I do...the bass player is hilarious, sings with his eyes closed, looks at the ground/lyrics while singing, and never ever looks at the crowd, even when not singing. Also, don't take this the wrong way as in no way am I slamming Jeff...he's great. Rob Halford was staring at the stage and walking around in circles the whole night at the Long Beach show in 2005. Wierd, I don't remember him doing that in the eighties.
