Disco Inferno: When disco dominated the charts

By Charles Apple

The 1970s were a time for polyester suits, platform shoes, giant gold chain necklaces and heading out on the dance floor to “shake your groove thing” to one of the many disco songs that seemed to form an endless chain marching from your car radio.

The disco era reached its peak July 21, 1979 — 45 years ago today, July 21st 2024 — when the top six spots in that week’s Billboard Hot 100 were all occupied by disco singles. At No. 1: Donna Summer’s “Bad Girls.”

Donna Summer's 'Bad Girls'

Donna Summer was a huge success: She scored Top-10 hits in the 1970s with “Love to Love You Baby,” “I Feel Love” “Last Dance,” “MacArthur Park” and “Heaven Knows.”

In 1977, she was working in the offices of her record label, Casablanca Records in Los Angeles, when she sent her secretary over to Sunset Boulevard on an errand.

When she returned, the secretary informed Summer that she had been detained by police, who had assumed she was a prostitute.

This angered Summer. But it would inspire her to write a song for her 1979 album. “Bad Girls” would become the album’s title track.
