The reason Puff Daddy, or Diddy even, is at the top of the game, is that he knows the hip-hop business like the back of his hand and understands the path that his Armani-clad feet need to tread. And if he needs to swap the Armani for the old-school Nike of Tinie Tempah and his mate Tinchy Stryder in order to step into the grime arena, well, so be it. This has come about though popular demand on his Twitter for a version of “ Hello Good Morning” (which in its original form featured T.I.) that is the advance single from “ Last Train To Paris ” ( Interscope), the fifth album by the New Yorker expected by 20th September. The record will include collaborations with Jay-Z, Lil Wayne and Justin Timberlake.
