This reminds me of a fun bit a couple radio buddies and I did back in the early 80's.
I was on KVIL at 11:00 at night and my buddy Al Forguson who was doing nights at KMGC (102.) called and while he and I were talking, Mike Roberts over at KNUS (98.7) also called. We had a conference thing on the control room phone and so I conferenced all 3 of us together and we decided to see if anyone would notice if we all played the exact same song at the exact same song. We started going down the list of currents and realized we all 3 had Kim Carnes "More Love" in rotation, so we backtimed perfectly and counted down, "3, 2, 1, hit it!" and all started the song at the exact same time.
It was so funny watching the phones blow up with people saying, "heyyy, you're not going to believe this but....you guy, Magic and K-News are all playing the same song right now..."
Little did they know!
..good times, good times.
