Billy Gibbons of ZZ Top has found one of the nice things about showing up unofficially to the South By Southwest music festival in Austin is he can pop up wherever he wants.

 He jumped onstage with the group The Cringe during their set Saturday. On Friday, He showed up unannounced to Rachael Ray's free food event that also featured Wanda Jackson and Fitz and the Tantrums.

 He was also selling his hot sauce, BFG 44. The slogan on it is, "Have Mercy. Shake Well."

You can catch ZZ Top as they roll on with their North American tour.  They will be in Oklahoma City at the Zoo Amp Theatre on May 14th.  Tickets go on sale for Fan Club Members on March 22nd and to the general public on March 25th.
