Ha! The concession workers probably brought their 45’s in and put them on the stack on the record player over the PA! Loved those days!
I was a kid (8) in 1977, but remember the song well at the pool where they played Top 40 all day. rip
No! top 10 radio in Chicago.
And when I say top 10, I mean 10 songs is about all they ever played.
3 hours at the pool and I probably heard Rhinestone Cowboy 5 times.
Do that 2-3-5 days in a week, throughout the summer.
