When I was younger- a lot younger- I heard a lot of people talk about wishing they'd have seen Kiss in 1977 or Elton John at The Palladium or some-such unforeseen legendary show post facto.
I'm here to tell you that my wish would be to have seen The Ting Tings in 2008.
The Ting Tings @ Route du Rock (Full set, 16/08/2008) (youtube.com)
What a gem.
Big thanks to Thadeus Butler who turned me on to The Ting Tings.
