"Every Night" was written by Paul McCartney while he was on holiday in Greece, and first released on his McCartney album on April 17, 1970.
Every Night is a long-time favourite Macca track of mine. Why? Just so, but the lyrics have a calming effect that resonates with me; I like to be home too. And the chords changes are great too.
But overall, the appeal form me is how the lyrics and music are completely aligned; you could feel much of the emotion of the song from the music, even if you didn't know the words.
This starts by droning the low E on the opening bars. Although the E chord seems to alternate to a sort of Bm7 chord, this is all done by changing just 1 note in the chord. In concert, Paul just lifts his pinky here from the high E string, nothing more. This prolonged E sound is the 'home key', and fits beautifully with the concept of staying home in the lyrics.
The long E sound creates tension, and we then get a quick succession of chords that suggest a move to the key of A. (Listen to Mull of Kintyre for a similar move just before the bagpipes come in). But before we really get there ("and every day I want to do"), Macca plays a F# major, instead of the F#minor. The major chords drives us directly back to the key of E. Again, this marvellously reflects the lyrics: he thinks of going out (moving to the key of A), but quickly decides to stay home (in the key of E).
The 'middle eight' is ultra simple: no lyrics, just 'woooooo' and a simple blues chord progression. Did Macca run out of creative ideas? I don't think so. I suppose he liked this simple section to reflect the simple pleasure of staying at home with his loved one. He doesn't want to DO anything, just BE there. What better way to express this?
Macca may have been inspired by Bob Dylan's "Tonight I'll Be Staying Here With You", which expresses a similar sentiment; and it has a long E7 chord to start-off with. You can midrash on the lyrics if you will: is it about a life in the Beatles, versus living & performing with Linda?
So there you have it. The BDJ singers cover Every Night, basically emulating Macca's version. Who could do better?
