Which disco version of Star Wars music hit No. 1 on the Billboard Hot 100 in 1977?

The disco version of Star Wars music that reached No. 1 on the Billboard Hot 100 in 1977 was “Star Wars Theme/Cantina Band.”

The record was made by Meco, the name used by musician and producer Domenico Monardo and his studio team. It combines John Williams’s main Star Wars theme with music modeled on the Mos Eisley cantina sequence, transforming orchestral film music into an extended disco instrumental.

The single reached No. 1 on October 1, 1977, and stayed there for two weeks. It came from the album Star Wars and Other Galactic Funk and was later certified platinum in the United States. The success reflected both the film’s cultural impact and disco’s enormous presence on radio and dance floors.

The answer is sometimes confused with “Star Wars (Main Title),” the original soundtrack recording conducted by John Williams. That version also became a hit, but Meco’s disco medley—not “Cantina Band” alone or “Imperial March”—was the chart-topping No. 1.
