Ok, I don't know much background to the act, so I'll just say what I've been sent about Mr Day.
Apparently Mr Day is lead singer of The Dynamics and has just released his debut album entitled Small Fry on Favorite Recordings / Groove Attack. It's described as 'an original blend of Soul Funk and Pop'.
Anyway, check out the video below, the song is pretty decent. He's got a MySpace page for more information and tour dates here.
