Wow I didnt even get it....I thought it was talking about something from the bomber! Dont know the song so cant go by that either.
Anyway, yes, its a jukebox ref.
But our jukebox wasnt quite that way. The AMI used a wheel so there was no stack. Just plain numbered all the slots in order by 10s with letters to separate.
What amazes me is the diners where there with the remote stations with speakers and individual booths. Five tables could request 4 songs lets say. Deposit the money for the 20 choices. The machine would play them in the order they were in the rack. My first song from a jukebox was Hey Jude. Something like that would get maybe 5 people requesting from the 20 count. The song only got played once, so high profit song it was.
