To all the detractors of the IL project to bring these artists to the screen try this little trick:
A) Bang on any of the DVD's,turn the sound off,and watch the energy in the performers.
I have always been a fan of any artist that puts energy into a tune (which you can do at 18 or 81 don't forget!) I personally reckon this quality is what sets NS apart - it covers slow as well as fast tunes but they ALL got energy!
By lip reading see if you can guess any of the tunes (sounds hard but if someone gives you a jumbled list of all the tunes/artists on the DVD you might well be surprised.) When either by knowledge/luck/elimination you hit on a right answer THEN turn the sound on and you will realise it's the artists we're looking at and their input - this time around I'm afraid the music is secondary.
We're lucky to have a chance to see even what these artists look like,never mind how they have weathered the storm of life.
Unless you can backdrop etc the same as you did 30+ yrs ago I'm afraid your criticism should be kept to yourself.
