I saw the clips of the gig on Youtube. I’m surprised it was a large venue – from the film it looked like it was in a hotel lobby somewhere. Then again there was no shots of the crowd.
I found “Long Way To The Top” where part of the audience is seen jamming at this show. Go to the 3:22 mark. Lu, band, and guests were rocking! LU herself was REALLY jamming on this song. It’s great.
