Proctor and Bergman are the comedians Philip Proctor and Peter Bergman, two of the four members of The Firesign Theatre. The two Midwestern members of the group performed as a double act for a while in the mid-1970s and recorded a few albums, though all four members continued to perform and record together.
In 1977, they were regulars on a summer replacement television series on CBS hosted by the Starland Vocal Band.
The screenplay for the 1979 movie Americathon was an adaptation by others of a play written by Proctor and Bergman.
