Definitely "To Give" and "Meat is Murder". Talk about mood killers. "Paris" needs to be retired too. Good song, just overdone. I think it's been played on just about every show since 2008.
On the opposite side of the coin, I was listening to music on shuffle today and "Mountjoy" came on and was followed by "Now my Heart is Full" and they worked beautifully together. I propose that combo of songs be played towards the end of the set on the forthcoming shows.
