First thing I did was to look for the A-Z lineup.
We HAD Artist / Stage / Day / Slot
Slot has been removed. I used that page to create my lineup sheet which won't be possible anymore, which is sad as I have them going back almost 10 festivals, used to remind us what we want to see and also what the hell we ended up actually doing!
EDIT: 2022 and back still includes the slot, here's hoping they don't remove that going forward!
