With an amazing voice like his, one could only imagine who he should do a duet with. I think it should be an English female singer. Perhaps Corinne Bailey Rae. Now that would be a beautiful combination of rugged and smooth soul rock.
yeah corinne's voice would be great. btw, he and jason mraz made a song together, maybe you would want to listen - their voices blended to perfect. :)
