This song finds The Vaccines' singer Justin Young getting worked up. He told NME: "This is about as angry as I'm willing to show people I'm capable of getting. Again, it's pretty direct. It's about someone taking himself too seriously and how that wound me up. It's me saying, 'let it go.'"
"(What's So Funny 'Bout) Peace, Love, and Understanding" was written by Nick Lowe in 1974. The original version with his group Brinsley Schwarz was kind of somber, but Elvis Costello made it a classic with his 1978 uptempo take.
