San Francisco rock group, not the founding father. From Philip K. Dick's novel Radio Free Albemuth, written in 1976, but only published posthumously in 1985.
The lead singer is Grace Dandridge and they are on Arcane Records. Their song is "Come to the Party," which has been carefully written and constructed to deliver the subliminal message that fictional Nixonian U.S. president Ferris F. Fremont is actually a communist agent. They actually get the song on the air.
Main character Nicholas Brady tried to get the same song recorded by The Playthings when he worked for Progressive Records and had his career and label destroyed by the FBI for his troubles.
