'Boys will be Boys' is a fave of mine too!
I am sure I heard 'Run to Paradise' also by The Choirboys on occasion too...!
Other songs I have heard coming from the Diner Jukebox include: -
Paul Kelly - Dumb Things
Chantoosie - Kiss and Tell
Kings of the Sun - Serpentine
I really like the 'Won't Back Down' sound-a-like too (any clues on who it is by?)
One song I really like, but have been struggling to find any info on was played quite a bit in Summer of 1989 (epi. 311-381) had the lyrics
'.......on the right track,
There's a Monkey on my shoulder,
Take that chip right off my back,
....when I get back with you we're both gonna crack'
It's in Episode 311 (at 19:30-20:00, before scene change, going into the Summer Bay Classic 'Santa Never Stops in Summer Bay No More...!)
Anyone recognise it?
