 In 1982, Randi verified the abilities of Arthur Lintgen, a Philadelphia doctor, who was able to identify the classical music recorded on a vinyl LP solely by examining the grooves on the record.However, Lintgen did not claim to have any paranormal ability, merely knowledge of the way that the groove forms patterns on particular recordings.In 1988, John Maddox, editor of the prominent science journal "Nature", asked Randi to join the supervision and observation of the homeopathy experiments conducted by Jacques Benveniste's team.
