Speaking of the Hayride: It was the time when rock and roll was just starting to cross over from what was called R&B and the term bop or bopping started out as a bit derogatory, then became more acceptable.
At the beginning of the movie, Buddy is playing the acceptable country style music of the time and then introduces his own song saying "This is for the boppers ...those who bop". All the kids head for the stage and show their appreciation. I think I was in the 4th or 5th grade and we used to go to the soda bar at the 5 and 10 cent store and play the juke box and I remember getting scowls from older patrons.
yes
earlier in the 50s I think R&B that wasn’t the blues was called race music.
