Charles Laquidara was there at KPPC-FM (Pasadena, CA) when Tom Donahue took over and changed the station's programming to make it Southern California's first freeform station in 1967.
After the KMPX strike in 1968 and the move of Donahue and Crew to KSAN, Laquidara moved to freeformer WBCN-FM (Boston, MA) in 1969.

"The Big Mattress" was a morning show Laquidara developed, beginning in 1972, that became a Boston favorite for the next 2 decades and more.
