Oh, the happy days of hard-wired Unit broadcasting! I was a DJ/announcer on Tengah Broadcasting Service in the late 60s, where apart from links to BFBS [somehow, our programme controllers managed that somehow] we used a HUGE library of 33rpm and 45rpm records covering all genres from the Classics to The Goon Show
A happy band of volunteers, mainly airmen but with a couple of officers on the roster too. I still have my Selangor Pewter farewell tankard, suitably engraved and presented at a 'dining out' at the cinema complex in Orchard Road [the one with the car turntable at the main entrance].
