From Disney's Hollywood Studios Wiki
Bear in the Big Blue House - Live on Stage is a retired Stage Show with audience participation elements. It featured Bear and friends singing songs from their television show, Gear in the Big Blue House.
The attraction opened on June 7, 1999 and ran until August 4, 2001. It was soon thereafter replaced with Playhouse Disney - Live on Stage!, which features characters from several Playhouse Disney shows and was bookended by Bear in the Big Blue House segments, in both the first and second version of the show.
