John Travolta is responsible for the decline of both disco and country music (Urban Cowboy). Neither were the same after his movies came out.
I used to go to Gilleys in Stinkadena before Urban Cowboy came out. After the movie, the whole atmosphere changed and the place got absolutely packed. It never was the same after.
Then a decade later, Garth Brooks put the final nail in the coffin of country music.
Was great to watch an episode of American Pickers that had them coming onto Gilleys. Very cool to see what it turned out to be long term.
