Billie Joe Armstrong (The Sun, 2024): "Goodnight Adeline deals with depression. The very last line is about when I get my shit together, 'I know I’m going to climb my way out of this. I know I gotta wait for my Phoenix to rise from the ashes of this.' That song makes me think of singing in a stadium in England. It’s got a chorus you can really sing along to."

Fan interpretation: "The Adeline in this song is most likely the street in Oakland. Because it's such a long, significant street, it has a lot of bars and clubs, so the drunks of Oakland have spent a lot of time on and around it. However, the narrator could be talking to a person, not the street itself or his alcoholism – perhaps saying goodbye to them from 'the gutter' his face is in outside an Adeline Street bar as they walk away ('you're going to say goodbye and let it go') because he chose alcohol over them ('I'm going to drink my wine and let it go'). Or maybe he is saying goodbye to the street as a metaphor for trying to walk away from his alcoholism, but it's too late; the subject is already gone and he gives in again. Since it comes before Suzie Chapstick on the record, that could be who he's talking to. The goodbye in this song could be the prequel to 'will I ever see your face again?'"

Fan interpretation by Cris on GDC: "I've always interpreted as it being about him trying to say good bye to alcoholism. The 'I'm gonna drink my wine and let it go' being like 'I'm gonna have my last drink, and start being sober tomorrow,' but then not quite following through (when you're (supposed to be) sober, but you still 'wake up with a hangover') and knowing that sooner or later he'll have to say goodbye for real."
