Acoustic Rock Song.

There's one song that's been bothering me for awhile. It's a song I heard on the radio some years back. it was an upbeat acoustic rock song. Possibly with ties to folk or indie as well. The singer was male and had an almost falsetto voice. Because of the feel of the song it could have been in the 70s or even 2000s it's hard to say. The only thing I can remember from the song is the chorus, which is both distinct yet sadly hard to search...  The lyrics went something like "You And I, eye-eye-eye-eye-eye" I don't know the exact chords but I think the eye's go from major to minor chords and down a scale each. I'm not too knowledgeable on notes so I could be butchering it but does anyone have any idea what I'm talking about? The eye-eye-eye's were like the main hook of the song. This song's been stuck in my head for a few years now!
