Barenaked Ladies played a private concert at Yerba Buena Gardens for the WWDC Bash — formerly known as the Campus Bash. Every year Apple schedules a band and keeps it a secret until they take the stage. Prior year bands have included the Wallflowers and Ozomatli. The Bash used to be held at the Apple Campus. When Apple moved WWDC to the Moscone in San Francisco they continued the tradition by chartering a hundred busses to drive 5000 people to San Jose. After a couple years of this the Bash was moved to Yerba Buena Gardens.
Barenaked Ladies showed themselves to be real geeks as well as fans of the Mac. They changed the words to several of their popular songs for the target demographic.
