In a 1954 song, country artist Jim Reeves sings the line "Beatin' on the ding dong all day long." Did this mean something specific in the 1950's?

I apologize if this is kinda puerile, but not knowing is driving me crazy. At the beginning of the song, he sings:

"Beatin' on the ding dong all day long/ I go around just singing this song/I got a gal, maybe two or three/ Beatin' on the ding dong don't bother me"

He then goes on to say:

"Beatin' on the ding dong don't mean a thing/ Just some words that you can sing/ Makes no difference if they're right or wrong/ Beating on the ding dong all day long"

which seems to suggest that it's just a random ditty that he sings. I guess this could be taken at face value, but it just doesn't strike me as a sentence that's just word salad. Did ding dong mean something specific in the 50's? Is there some wider context that I'm not getting?

Edit: I feel like I should add that there's a sound kind of like someone hitting a tin pan that features prominently throughout the song.
