Chord/Tab song: Swing Tree

I'm really into this band, Wes and Rostam work wonders together.
This is "Swing Tree", which is extremely simple
( Tab from: http://www.guitartabs.cc/tabs/d/discovery/swing_tree_crd_ver_2.html )
[Bb]If I was a boy at sea I would be
[Gm]Swinging from a broken tree I would be
[Bb]Down on my back looking
[Gm]Up at stars at night

Repeat the Bb- Gm progression over and over throughout the song, it doesn't change.

Nifty right?
Remember, you can stream the whole album at dscvry.net.
