I know in the 80's a format change happened a couple times with me.
First time no staff changes..as the company was cheap..

Went from top 40 to Album rock with Burkhardt Abrams consulting.
That was about 1980. Burkhard Abrams rep Jon Sinton(of Air america)
came in and put paper card index files together for the music. Dubbed it from vinyl on to cart. We played some from vinyl too. He was real anxious to
get us on the air with the format as the ratings were beginning soon in Oct '80.
I liked working with him. He helped me alot with my airchecks.
I thought I sucked and he said I was good. He told me back then their
was a woman on WYSP in Philly. I don't remember who that was. Maybe you guys would.
A station I know in '80 went from FM Beautiful music to top 40FM overnight.
Rumors were going around before the switch for a few months..as to who would be on the air. They took a jock or two from a competing AMTop 40 station so those two knew what was going on. They did it on new years eve '79 and called it the station of the '80s.
That was pretty shocking to the beautiful music listeners next day. But it paid off for the owner..
In 86 at a top 40/Urban in FL..I was basically laid off so to speak when the new company took over. Their GM had told me I would be kept in some capicity.. an air shift..but wasn't. The PD had no plans for me.
The new guys were staying in hotels nearby I think. The format change happened on a weekend..sat morning. Most of the music was in house.. They didn't change too much just less Urban.
In NYC...
Stern took over after Jay Thomas at WXRK( which changed to rock I think from what ever Jay was playing..top40 I guess)
(Stern was on in the afternoon I think first and then mornings..)
I think Jay was taken in the day before or that morning and fired..
Stern called Jay at home after he was fired.( I have an aircheck of that.) and the bit was really funny. Stern was playing Jay's old corny drops he had left in the studio.
Jay told him not to play them as they were "copywrited"..
The drops sounded cartoonish to me. No wonder he got fired.
Jay has had his moments..but he is an actor at heart..
I think format change plans were and are still made in advance most of the time and hushed up ..
Stations for sale used to be a tip off .....and most jocks looked for jobs when they found out. AS for the music, I guess they just got record service from the record companies for whatever format they wanted..or bought it at stores if they were keeping it a secret. Cheap stations got music from the jock's collections also and just dubbed it off.
Those are the ones I can remember.. Guys who worked in the 60's and 70's may have another story to tell.
