Fall Out Boy's secret show on August 31 at Angels & Kings in their hometown of Chicago, IL was recently discussed in a post on the Friends or Enemies website.

The band performed under the code name 60xxx to 86 members of Fall Out Boy's fan club, the Overcast Kids.

They also apparently referred to themselves as "Boner Party" at one point.



In related news, Pete Wentz mentioned in a recent Playboy issue that he and wifey Ashlee Simpson are "90% sure it's a boy," referring to his upcoming parenting debut.

The interview also finds Wentz admitting participation in a game of Russian Roulette and describing the bassist's struggles with depression.
