The band did an extensive track-by-track breakdown of their most recent record
Wake Up, Sunshine. In one of the parts of the album breakdown, Gaskarth addresses how the bridge developed. You can hear him talk about it around 42:40 into the video below.
“This one’s really interesting. There’s a couple of cool twists and turns on this one. The bridge, which I’m sure some people have picked up on and pointed it out, the bridge melody is lifted straight from a Used song,” says Gaskarth.
He elaborates on telling the Used frontman Bert McCracken about using it and the context for why it was used.
