the final US number one for all but John (John would have two more US number-ones during the 1990s). Due to Wonder's involvement, it also holds the distinction of being the last number-one song for anyone who had topped the charts before the British Invasion (his first number-one hit, "Fingertips", came in 1963). Outside the United States, the song topped the charts in Canada and Australia and reached the top 10 in Ireland, New Zealand, Norway, South Africa, and Sweden. On the UK Singles Chart, the song debuted at number 49 and climbed to its peak of number 16 three weeks later, staying at that position for another week before descending the chart. It remained in the UK top 100 for a further five weeks, totaling 10 weeks on the chart altogether. The Dionne and Friends version of the song won the performers the Grammy Award for Best Pop Performance by a Duo or Group with Vocals, as well as Song of the Year for its writers, Bacharach and Bayer Sager. This rendition is also listed at number 75 on Billboard's Greatest Songs of all time. Warwick, John, Knight, and Wonder performed the song live together for the first time in 23 years at the 25th Anniversary AmfAR Gala in New York City on February 10, 2011.
