Superman takes on Batman this week on WireTap. No, the two comic-book good guys don't suddenly decide to duke it out for supremacy. It's a debate between Jonathan and his thirteen year-old daughter ZouZou about which one is the better hero. Listen in as they try to put this age-old dispute to rest, once and for all. Also, Jonathan's father reminisces about his trip to Barcelona as a young man. That's WireTap, with Jonathan Goldstein, Sunday afternoon at 1 (1:30 NT, 4 PT) on CBC Radio One.
