Dick Clark did it only one time, yet it is one of the most widely remembered and treasured episodes of American Top 40 with host Casey Kasem. Clark was the guest on the show that aired the weekend of March 24-25, 1972 when Kasem took that week off. Clark was wildly popular at the time as a television personality, hosting American Bandstand on Saturday afternoons on ABC Television. For many listeners it was pretty surreal to hear him on the radio hosting the very hits he helped to make popular on his TV show. Clark had a more casual approach to his hosting style on AT40, in contrast to Kasem's more straightforward delivery. Clark always held the same calm but likable demeanor on his television programs.

In his memory, Oldies 93.3 will air the Dick Clark episode on Sunday, May 6 from 9:00 a.m. to 12:00 noon, the usual time slot for the classic AT40 shows.
