[2] On June 14, 1950, AM radio station DZBB began broadcasting from a makeshift studio on the 4th floor of Calvo Bldg in Escolta, which was then the business district of Manila.
During the first five years, the studio was barely surviving but a friend from the United States gave Stewart a good deal on American syndicated TV shows which defined the station's programming in the 1960s.
Aired on Saturday mornings, the show made Stewart every child's favorite uncle,[5][6] also featured two sidekick puppets - Spanky the elephant and Pancho the worm.
[3] From 1978 to 1986, Stewart hosted a musical show which debuted as The Maestro and Uncle Bob with pianist, composer and conductor Federico Elizalde on the piano.
The one-hour TV show featured Elizalde playing a variety of music from classical to jazz.
After Elizalde's death in 1979, the show was renamed Uncle Bob and Friends, with mainstay pianist Joselito Pascual.
[9][11] His son, Robert Jr. ("Jody"), continued with the children's show during the remainder of the 1980s (renamed The New Uncle Bob's Lucky 7 Club).
