Olivia Newton-John Have You Never Been Mellow (Live 1975)

History and Release. In March 1975 the single became Newton-John's second consecutive number one hit on the U.S. Billboard Hot 100, although it stayed in the top chart position for just one week. The record also received a Grammy nomination for Best Female Pop Vocal Performance. The song also topped the Billboard Hot Adult Contemporary Singles chart and — in her continued success as a crossover artist — peaked at No. 3 on the Hot Country Singles chart. In the United States, it was Newton-John's fourth straight single to be certified gold for sales of one million copies. "Have You Never Been Mellow" also reached number one in Canada and peaked at number 10 in Australia and number 26 in Japan, but was not much of a success elsewhere in the world, failing to chart altogether in the United Kingdom. Cover Versions. The song is being performed as part of the 2007 Broadway musical Xanadu. Along with her later single Xanadu, a remixed version by "The Olivia Project" appears in the Dance Dance Revolution series of video games. The Dutch band Party Animals sampled the song in 1996 on their hit "Have You Ever Been Mellow". The song reached No. 1 on the Netherlands singles chart.
