When I was at 101 (when it was Eazy 101 and I'd been hired to be a live jock), I'd occasionally get called in to do the always-exciting overnight shift. I recall the music logs being identical, all 24 hours, to what the live jocks were playing. The music decisions were made by some satellie outfit way out west.
A few overnights when I got dragged in to attend another of my early funerals, I'd get gay and reverse some of the 3-song sequences by loading up the numbered, matching studio carts in the wrong order. EZ enough to do.
Of course, the satellite jock would then, calmly outro the delicately researched set backwards.
No one ever called ; I never got a memo.
That was in the days before RDS, HD, and even Prodigy. The station got to #1 with a 7/1 share. I half-kiddingly asked the PD about a raise, insisting that I was responsible for that .1 showing.
