Regarding the composition of this song, Billy Steinberg told us: "Tom started to write the chords and the melodies on an acoustic guitar at my house. The bridge to the song, or the middle eight as the British would say, the part that starts, 'Say my name, sun shines through the rain,' that part in particular is very Beatlesque. Tom, who's a great lover of harmonies, worked with Susanna to create almost a tribute to The Beatles and Beach Boys background harmonies in our demo and the Bangles recreated them on their record. One of the unusual things about that song, which is also attributable to its Beatlesque roots, is the fact that it really doesn't have a chorus.
The part that starts, 'Close your eyes, give me your hand, do you feel my heart beating, do you understand,' that part sets out to be the verse of the song and then the title is incorporated in the last line of the verse when it says, 'Am I only dreaming, or is this burning an eternal flame.' By the end of the song when all the Bangles chime in and re-sing the first verse at the end of the song, the whole verse feels like a chorus. The Beatles used to write in that way, for example, 'We Can Work It Out
.' The line, 'We can work it out,' is sort of a tag in the verse. The verse ends with, 'We can work it out, we can work it out.' It isn't a chorus, it doesn't begin with the line, 'We can work it out,' which would be more traditional pop hit structure.
The whole song 'Eternal Flame' is so melodic that it doesn't really miss a traditional chorus, it just works the way it is. In one more Beatle type arrangement decision we do the bridge after two verses and then there's a guitar solo and then we do the bridge again. Again, The Beatles would often do that. In the song 'We Can Work Out,' the bit that begins, 'Life is very short, and there's no time for fussing and fighting my friend' - I think that happens twice in the song. Sometimes if you have a bridge that's really good, it's nice to repeat it, and also if a song doesn't have a traditional Pop chorus you almost need to repeat the bridge so that the song is long enough and that's what we did in 'Eternal Flame'."
