Where in the World Is Carmen Sandiego? is a children's television game show loosely based on the computer games of the same name created by now-defunct Brøderbund Software. World aired on PBS from 1991-95 and starred Lynne Thigpen as "The Chief", Greg Lee as "the ACME Special Agent in charge of training new recruits" (renamed "Senior Agent" for Seasons 3-5), and Rockapella as the house vocal band and comedy troupe. Rockapella featured Sean Altman as tenor, Elliot Kerman as baritone, Barry Carl as bass, and Scott Leonard as high tenor, with Jeff Thacher joining in the fifth and final season as vocal percussion.
