Career
At WBAI, Efron was a frequent guest on Steve Post"s & Bob Fass"s shows, along with left-wing/counter-culture figures such as Paul Krassner. One memorable broadcast had Efron and Krassner filling in for the vacationing Fass, and identifying themselves as Columbia University students who had taken the station over as part of the Columbia University protests of 1968. Although regular listeners were very familiar with the voices of Krassner and Efron, police officers responded three different times during the broadcast to reports from listeners who thought the "takeover" was a legitimate event.
Efron also produced features of his own such as A Satirical View.
Marshal Efron is the author of a number of children"s works such as Bible Stories You Can"t Forget: Number Matter How Hard You Try. He also starred in the Sunday-morning television program Marshall Efron"s Illustrated, Simplified, and Painless Sunday School on Columbia Broadcasting System from 1973 to 1977.
