Knights Of Cydonia - vocal track?

[CauliColin]

Hi!
My drummer brother, my guitarist friend and I were planning to record Knights Of Cydonia (Muse), but we were hoping to add a vocal track to help the guitarist and drummer with the structure of the song, so we don't get lost. Does anybody have any suggestions as to where we could find a track? Preferably with a click-track backing for the drummer, please!
