I went to all three of the final nights in London 2022 - and while it was incredibly emotional objectively it wasn't the best gig. Twickenham 2007 was probably best - partly because I had such good seats and it was a lovely summer evening. I did a few gigs in 92 as well but I think the 07 setlist was better (as were my seats).
I've seen Gabriel a number of times but Earls Court 93 was absolutely phenomenal - an incredible concert. I've done Collins and Mike a few times too but Gabriel 93 and Genesis 07 are the ones I really remember.
