Here's how I played the main riff, originally a piano part, on my Washburn D10SCE acoustic. Note: this is the first time I've put tab online! It's not very exciting tab, as the part is very simple - all that changes is the bass note.

Luke's lap steel was tuned to an open G chord, and Robert played his recently-constructed percussive frame from which hang a multitude of cheap wind chimes, keys, washers, random sections of metal etc etc. Robert and I sang unison lead vocals, and then Luke added a melodic flute part during the middle and ending, to top the whole thing off.e|3-2-------------|----------------|B|----3-0-3-------|----------------|G|----------0-2-4-|--0--2--4-------|D|----------------|--0--2--4-------|A|----------------|----------------|E|0---------------|----------------|
We recorded the song on our 8-track, and then ported it into Buzz where I added plenty of the Sonic Verb plugin to give a bit of distance.
