Trivia: What was 1975’s longest-running Billboard No. 1 hit?
Shining Star
Love Will Keep Us Together
Lady Marmalade
Fame
The correct answer is Love Will Keep Us Together
So why is this answer correct? : Captain & Tennille’s “Love Will Keep Us Together” topped the Billboard charts from June 21 to July 18, 1975, marking the year’s longest run of any song at No. 1. “Shining Star” by Earth, Wind & Fire, “Lady Marmalade” by Labelle, and “Fame” by David Bowie were also No. 1 hits in 1975, but didn’t top the chart for as long.
