Not necessarily “dead air” but in the days when there was no automation, I was doing nights on a Friday night at The Planet in Lincoln and the overnight person didn't show, and then part-time person on at 6am was sick... and the program director was out of town (pre-cell) and no one else picked up, so I was on the air from 7pm Friday to 1pm Saturday... playing every CD and segueing every element. lol. People forget what that was like.
