In 1960, George Carlin, with his comedy partner Jack Burns, arrived in Los Angeles and were hired at KDAY for their comedic stylings. They performed in area coffee houses when the radio station went off the air at sunset and were subsequently discovered and performed on "Tonight Starring Jack Paar". Carlin and Burns worked at the station for less than six months. In 1972, KDAY switched to album-oriented rock only to revert to soul/R&B in January 1974. KDAY moved its transmitter to Los Angeles in 1968, and concurrently upgraded to 50,000 watts day and night. FM stations such as KJLH grew in popularity in the early 1980s, cutting into KDAY's audience. KDAY fought back by hiring Greg Mack from KMJQ in Houston as music director in 1983. Mack eventually added hip hop music to the station's playlist to appeal to mostly young Black and Latino listeners. Dr. Dre and DJ Yella Boy became the first mixer DJs at the station.
