I've enjoyed other tours more of Paul's than the WOA one-- mainly because of the additional Beatles songs, especially including "The End" and the over-the-top crazy, never ending guitar jamming that closed nearly every show from the '89 tour till now.
However, NOTHING beats the opening of the Wings Over America tour. I saw the two shows at Madison Square Garden, and when the lights went down, and the opening chords of "Venus & Mars" began playing in the total darkness (although you could see feint silhouettes of the band if you looked hard enough), the goose bump meter went off the charts. I was 18 at the time, and went to see the show with a good friend of mine, driving the 200-plus miles down Rt. 17 (it's Rt. 86, now) from Horseheads, New York.
Then, when the song exploded into "Rock Show," and the lights went up, and there was...well...there was f***ing PAUL f***ing McCartney standing there, playing bass, and SINGING just a hundred or so feet away from me...the rush of that moment will never, EVER be duplicated. I am not ashamed to say that I was so overcome with emotion at that point, tears ran down my cheeks. If someone had asked me my name, I wouldn't have been able to say a word. My mouth might have moved, but nothing would have come out.
I was a Beatles FANATIC at that point, and Paul was my guy (and has been forevermore), and that was one of the highlights of my life at that moment. And remains one of them to this day, over 35 years later.
in years to come/they may discover/what the air we breathe and the life we lead are all about/but it won't be soon enough for me
