As a music writer, I have seen hundreds of gigs, but best by far was Springsteen on 4 July 84 (I think the year is right) at Wembley.
Every single gig on the Born In The USA tour - which lasted two years, was started with that rabble-rousing song, except this gig. They played 'Independence Day', then carried on with the rest of the set. Nothing was said, they just did it, and if you know the song, you will know why I was blubbing like a girl by the end of it.
Unforgettable.
