Rootsy male/male duet songs needed

Details:

CHRIS JAGGER (Duets Project)
Producer/artist Charley Foskett has added Mick Jagger's brother Chris to the list of artists he's recording duets with for a charity album in aid of MacMillan Cancer Support.
STYLE: Strictly male/male duets in a rootsy style, top songs with great top lines and lyrics. Think Willie Nelson/Tom Waits (Charley) meets Mick Jagger (Chris).
Only your very best one song please.

Full publishing or at least sub-pub should also be free for the said recording.

Music Gorilla will be screening.
