Trying to think of realistic options of who we could get 2nd/3rd or even lower on that day and would be happy being under someone like Sam (not a dig at him but a smaller header) plus touring/fit the day and came up with:
HAIM
Oscar & The Wolf
Pulp
Biffy Clyro
Tate Mcrae
Wolf Alice
I ran out of ideas…. And tbf, it’ll prob just be 2 random names opening the stage or elbow moved.
