Calling All Mashup Musicians

I have a song stuck in my head. This song exists.... sorta. I keep hearing the vocals from The Raconteurs track "Steady as she goes" mixed with the melody of another song. The two play in perfect harmony.... but it's only in my head. I've looked at trying to make a mashup of the two, but extracting the vocals from a song is a difficult process as I've come to discover.

I extend my hand to the blogosphere, asking for help from anyone with the chops. I need the vocals from "Steady a she goes". Let's collaborate. Email me at hooliosphere@gmail.com
