This is from the flip side of Tara Jane O'Neil's new single, Sirena. It's a pretty straightforward Rainbow Connection cover. Maybe a little more reverb-y on the vocals. It's really nice, though I like her voice a lot.

I just heard this for the first time today and I love it; it's like a full blown Prince song. I don't really know anything about Niki & The Dove, other than they are from Stockholm and their first album, Instinct, just dropped. Also, you can go to their Soundcloud page to listen to more music. Look for the drum machine version of this song, it recalls Stevie Nicks' Stand Back.
