8pm at night is a crap kick off time? It's been used for decades.
I think the last Euros to kick off mid afternoon was Euro 96 (even that might be wrong). The last WC to kick off early was 1994/2014 but that was due to the European core audience.
You rarely see teams with change home shorts nowadays.
We used to wear the B&W with white shorts or white socks in the event of a clash but it seems away kits are now worn in the event of any clash or for marketing purposes.
