History Detectives: Fitness, Flappers and Phonograph Records

The voice on these 78rpm records is the grandfather our contributor never met. The 1920s albums play music with Wallace Rogerson giving exercise instructions. She asks HISTORY DETECTIVES host Tukufu Zuberi to tell her more about her grandfather. Was he the Jack LaLanne of the 1920s?
