This former A list singer has been singing in groups since he was a teen, but achieved his greatest fame as a solo artist. He used to be one of the biggest acts in the world and his trying to claw his way back to the top. One way he will not be doing that is with his former tour director. Everyone in the industry recently thanked this tour director for all the work he has done for them. Everyone that is except for our singer who chose not to publicly thank the tour director because he is jealous of his fame and I also think perhaps a personal relationship gone very bad.
