Diddy’s Dirty Money project appeared on David Letterman’s show last night (Dec. 14) to perform “Coming Home” from the Last Train to Paris album. This is a typically grandiose but mostly unremarkable Diddy track that he’s been focusing on recently to hawk copies of that new record, and is probably most remarkable for an unintentionally amusing (and rare) shot of the aging Letterman audience throwing their hands up in the air while still seated. Tough crowd. Letterman was naturally more receptive at the end, but even he neglects Diddy to paw all over the female members of Dirty Money.
