When I saw them on Sat night at Wembley Lindsey was def. drowning out Stevie and at one point she turned sideways to Lindsey and said 'turn it down' and did a downsign with her palm facing downwards.
shame
She didn't look like she was on medication, but she didn't look really happy on Sat night, and she did forget the words on one song, and came in late on another - but to me she was and always will be bril. I quite like seeing a few non-perfections - makes them human!!!
