Most of the BBC’s radio stations will come together tomorrow at 17:33 to broadcast an audio pastiche from Damon Albarn, celebrating 90 years of BBC radio. (Hopefully, they will find a manager to authorise this in time.)
This is the first time (nearly) all the BBC’s radio stations are broadcasting the same thing. However, some of them often come together to broadcast the two minute’s silence on Armistice Day or Remembrance Day. And in 1978, those of use old enough will remember “Radio 10” or the “All Network Service” on December 22nd when the ABS union took industrial action. This was a common service for Radios 1,2,3 and 4.
