If you've just woken up from that stranglehold that JBL put on you, you're still in the Toyota Center. Relax. Call the boss and tell him you won't be in today. You'll be checking out the Wiggles, Australia's kid-friendly pop entertainers who, unlike Barney or Elmo, don't induce suicide in older audiences. You may have heard their "Head, Shoulders, Knees and Toes" tune done on commercials and the like. No matter. After the violence you witnessed last night, these blokes will be a breath of fresh air, mate. 3 p.m. and 6:30 p.m. today and Thursday, August 5. 1510 Polk. For information, call 713-629-3700 or visit www.ticketmaster.com. $15 to $30.
