Los Angeles Mayor Richard J. Riordan probably won’t give up his day job, but he’s making his professional stage debut this week. The mayor has a cameo role as a blustering American millionaire dad in L.A. Theatre Works’ live radio theater production of P.G. Wodehouse’s madcap British comedy “Thank You, Jeeves.” He’ll share the stage with leads Jennifer Tilly as the millionaire’s daughter, Simon Templeman as good-natured, upper-class bumbler Bertie Wooster and Paxton Whitehead as Bertie’s ever-resourceful valet, Jeeves.
