The two work together well on "Let The Show Begin." Cam remains gruffly charismatic in his career's sunset years, while Estelle retains the flighty vocal pipes that first enamored her to these shores.

Introduced by a spoken word section from Couzin Bang, Estelle kicks things off by comparing herself to Tina Turner, Diana Ross and Erykah Badu, like the R&B version of Rick Ross' "MC Hammer."

Cam'ron entertainingly apes her singsong flow, and comes through with a hilarious at an unnamed 40-year-old hater: "quit your b***hin', man / what you sellin', fossils?"
