Big doin's in town this weekend. No, we're not talking about Memphis In May Musicfest. We're talking about Rodney Herenton's birthday bash, er, bashes. An e-mail from Rodney's wife Andrea says there's a tuneup party at the Silver Spoon, then a blow-it-all-out "party of the year" for the Mayor's son at Senses on Saturday night. Rock on, Rodney.
