I think that dmg's comments about MK' voice are correct. Analysing the whole thing with a clear mind after the concert, he saw that MK, unfortunately, was on his lowest point as a singer and guitar player.
I remember going to see the Golden Heart concert in Leeds 1996. It was the most wonderful concert and I still remember it to this day! I was walking on air for weeks afterwards! I would have loved to hear a recording of that concert, but we didn't have official recordings at that time. Maybe there was a bootleg, but I never found one.
These days we do have official recordings of the concerts we attend, but the downside of recordings is that we can hear all of the glitches, etc which we didn't notice at the live concert. If there were mistakes and glitches at the GH concert I attended in 1996, I was unaware of them, but it is still in my head as the most wonderful concert.
I wouldn't want to be without the recordings I have of the concerts I have attended and I still listen to them, but nothing can beat being there and enjoying the whole atmosphere of a live concert without having post mortems later! The recording of the Leeds concert in 2019, I'm happy to say, still gives me great pleasure as do so many others!
