I'm sorry to say that Mr. Cohen passed away ten years ago.

He was at my former favorite station KRLA which I listened to up until the early 70's when I finally got my own FM and could tune in to K-MET. By the time of his PD there, KRLA was in the A.M. slumps. In L.A., the Boss Radio KHJ AM was the king until AOR and KMET took over. KRLA was the cool choice and did very well until the 70's. By the time of his PD, KRLA dropped their coolness factor and became a Boss Radio clone to little avail. It floundered as a copycat.
The nail in the coffin for top 40 AM came in the form of KIIS FM. KIIS took over for top 40 and secured their position with the hiring of Rick Dees. I can't remember if that was during his tenure or not, but by then and for sure, KIIS was No. #1 for Top 40 hits, even besting local legend "The Real Don Steele" who worked at KIQQ FM to little avail.
Something that many people are not aware of is that Led Zeppelin lived in L.A. in the late 60's/early 70's. At the start in the late 60's they were playing weekly gigs at The Whiskey-A-Go-Go. Which is where the song "Goin' to California" probably comes from.
The Beatles owned a house in L.A. by 1966.
And Supertramp lived in L.A. up until '77. Roger Hodges' brother Nick lives somewhere in California. And Mick Fleetwood owns a restaurant and tavern here, and was unsuccessful in trying to resurrect Laserium at The Vine Theater, trying to do it as a movie theater experience on a standard movie screen instead of doing the glorious Griffith Observatory Experience in the Surround.
And my foggy memory. Elsewhere I linked Wolfman Jack to "The Mighty 690"
but apparently that should be "The Mighty 1090"
And I'm still trying to place the significance of the VHS dupe of Rod Stewart's "Hot Legs" which I delivered (while working at Image Transform)...to the Warner Bros. Home Office, being told that "it was the air print for that week's "Midnight Special". And yes, "Hot Legs" aired that week and I didn't question it at the time, but would they actually use a Stock Home-Grade VHS Cassette for a network broadcast?
Why wouldn't it be a pro cart/ U-Matic cart or pro-reel?
Image Transform was a video shop specializing in pro color correction and noise reduction using electronic and video transfer schemes for film, even for films such as "Apocalypse Now!"
They were best known for processing the blue screen FX for NBC's short-lived series, "The Invisible Man" starring David McCallum.
