I saw Wings in Detroit during the Wings Over America tour in '76. One of the best McCartney concerts (except for the dreaded feedback on some of the speakers) until the 2002 tour. Anyway, I bought the Blu-Ray looking forward to watching this concert. As the sound goes, it was great, the band really rocked. As for the picture quality, I was a little disappointed. Many of the crowd scenes were very grainy. Close ups of the band looked good, especially McCartney, could not believe how young he was and how much energy the guy had (still, he was almost 32). I really thought on Blu-Ray the concert would look fantastic, it did, except for the several grainy shots. I suppose even with today's technology, depending on how the concert was filmed, McCartney's people could only do so much. As for the music, it sounded fantastic, better than I remember. This band rocked on stage, some songs sounded better than in the studio. Still, I am grateful they released the entire concert, with all the songs included. Actually, I watched this concert and right after, watched the "Wings Over America" documentary, "Wings Over The World" (the '76 tour). What a combination!!! Now, I am beginning to under why my younger cousin (age 12) said back in '76, Wings are better than The Beatles. (Of course, he was wrong, but, I won't hold that against him.) Many thanks to McCartney for releasing this great concert.
