@Huff , I'm gonna jump in here---Bobby Ocean left KFRC for KHJ in May of '75. Rick Shaw replaced Bobby in Noon-3.
Ed O'Brien moved from 10p-2a to 2a-6a when Beau Weaver moved into the 10-2 slot in October of '74 (he'd been in mornings for six months until DDR's arrival). Ed was replaced in 2-6 by Shana in September of 1974, and Beau, who left for KILT in Houston, was replaced by Don Sainte-Johnn. So it was
6a-9a: Dr. Don Rose
9a-12n: John Mack Flanagan
12n-3p: Rick Shaw
3p-6p: Chuck Buell
6p-10p: Marvelous Mark
10p-2a: Don Sainte-Johnn
2a-6a: Shana (Margaret Reichl)
That lineup held until April of '76, when Buell left. Flanagan moved to 3p-6p and Big Tom Parker came down from Portland for 9a-12n.
