Great job! Especially if you feel that your singing isn't good enough. To my ears you sound a lot like Milton C when you're singing the E Lu aye section. I like how it fits over the Reggae-swing feeling of the instrumental parts.
Thanks man... I'm actually a lot happier with the vocals in the later part of the tune. We've still got to cut the one at the beginning which is throwing it off (to my ear). Glad you gave it a listen.
