Nice collab guys. Really nice, breezy song. Perfect little melody and nice 60s-esque chord structures. Definitely understand the Joe Jackson comparison. It's pretty light instrumentally, but it works like 'Is She Really Going Out With Him?' I'm a fan of the upfront acoustic guitars but couldn't help pining for some jangly guitars in the choruses.
I think you've been way too light and reserved with the harmonies and backing vocals. In the chorus, I can hear the ghost of a harmony there but feel like it should be much louder, and maybe tracked. And why not add a third? You have the lush sixties chords but don't feel like you're making the most of them vocally. Same with the backing vocals in V2, the Ooh-La-Las. If it were me, I'd have those in block harmony too and louder in the mix. I just feel like if you're going to do it, you should REALLY do it, yknow?
Great tune.
