Josie and I got there early and went into the studio. Sean had the news break, so left the studio to have a nicotine break.
Josie and I started our normal chatter, which as you can imagine is not always as carefully phrased as when speaking in public. A short time into this, Josie then goes “Does that red light mean we are broadcasting?”.
Yes, Sean had forgotten to turn the microphone off. Very fortunate that Josie noticed the red light in time, as I suspect five minutes of our conversation accidentally broadcast would not have helped either of us!
