A young Bill Cosby visited the University of Idaho campus in May of 1966. 

The largest audience ever seated in the Memorial Gymnasium (approximately 4300 people) attended the Bill Cosby show May 14. The entertainment began with music by the We Phi’s, a University of Idaho group. Bill Cosby presented familiar cuts from his albums, signed many autographs, and was exuberantly applauded by a laughing crowd.
