Phosphorescent - Mermaid Parade chords

This song is pretty simple as it's really just the same pattern repeating over and over. 
As soon as i get lyrics I'll update but as for now just the chords.
[ Tab from: http://www.guitaretab.com/p/phosphorescent/226962.html ]
F - Gm - Bb - F 

All the way through the song theres both a lead guitar and a piano playing leads.
It's in the key of Dm/F. Just noodle around a bit in this scale and you'll be fine.
