Not her assistant. Not with the entourage. A local.
When she actually cranked through a song with the band, they were tight, she could scream the scream, and it rocked. But it reminded me of a Superdrag show where John was slightly tipsy and talkative. Show would hang until he got through his thoughts, and slowed the whole thing down. I edited those bits out, cutting 10-15 minutes from the show, and that then was amazing. Could see a one CD version of this show being great.
If you have ever seen the Butthole Surfer's live DVD "Blind Eye Sees All", Gibby's between song banter from early in their career was very similar to her's. Same gesturing too.
