This is too vague. It's still from the' 80 s I don't think there will be too many answers. I think the music that can be used as background music should be music. Band-Aid's music is too cheerful and will usurp the role of the host. Could it be Ode to Joy? In the 1980s, there was no TV station. I remember two songs that have been played during recess, one is light music "Picking Flowers" and the other is "Youth Waltz". I guess these two songs are more likely.
