Rivers Cuomo, co-founder, lead singer and principal songwriter for Weezer, is one of the writers on this song, along with Lambert and Greg Wells ("I Not Hook Up," by Kelly Clarkson).
Cuomo told Rolling Stone that he originally penned this for his band. He said: "It's one of my favorite songs I ever wrote. For some reason, Weezer didn't want to record it for Raditude. I figured it would end up on the next record and it just didn't fit this time around. Then I was invited to sit in with Adam Lambert and watch him sing, and he was checking out the song. And as it turns out, he came up with a few ideas for it for himself, changed the melody around, suggested some lyric changes and before you knew it, I was writing a song with Adam Lambert."
Cuomo told MTV News that this song draws from a fantastically eclectic combination of sounds. "It sounds like a combination of ABBA, with beautiful pop melodies, and a disco beat like you'd hear in a Donna Summer song," he said. "But then there is this heavy guitar feel to it, like from [German techno-metal band] Rammstein or something. It's just a wonderful hybrid of all the music I love."
The Prince-penned "Manic Monday" was the first song The Bangles heard coming from a car radio, but "Eternal Flame" is closest to Susanna's heart, perhaps because she sang it in "various states of undress."
