During Gandhi's stay in England in 1931, when the Columbia Gramophone Company  requested him to make a record for them, Gandhi pleaded his inability  to speak politics, and added that, at the age of sixtytwo, he could make  his first and last record which should, if wanted, make his voice heard  for all time. Confessing his anxiety to speak on the spiritual matters,  on October 20, 1931 he read out his old article "On God".
