Home turf for me, here's some thoughts.
Pre-gig pub? No need, the Brudenell caters to all your alcoholic and pie shaped needs. Feel free to pop into the Royal Park to prove my point. if you're coming by train and arriving early, then there are several good places round Leeds station - Leeds Tap & Friends Of Ham on New Station Approach, Bundobust (will be full), Head of Steam and Scarborough Taps (will be heaving if Leeds are at home, then empty at 3) on Mill Hill.
Offers of lifts? Over to you.
Spare beds? All gone at mine, I'm afraid.
Cheap digs? I'm told Leeds hotels aren't cheap at the weekends, but you're probably better off looking for a B&B in Headingley than in the town centre.
Spare tickets? Sold out, of course. Did Kevo have a spare?
Any other relevant info, please share. That's what we came here for.
