NEW YORK—During a recording session last Tuesday, rapper Dwayne "Lil Wayne" Carter appeared uncertain as to who else was being featured on his newest track, sources inside the music industry reported. "Yo, check it, we comin' at you with Method [Man] and Redman and uh, brother over there in the hat. Hatman," said Lil Wayne, whose single "O.G. Crunk" will be released later this month. "Okay, and we got this guy on my left, those two guys there gonna rock the mic, and, Dave, is that you?" The final mix of the seven-minute track reportedly ends with Lil Wayne handing the microphone to the participants one at a time and asking them to clearly state who they are and what they are here to do.
