Dionne Warwick's recording of "That's What Friends Are For" marked the first time she had worked with Bacharach since the 1970s, when Warwick felt abandoned by Bacharach and Hal David dissolving their partnership. Warwick said of their reconciliation:[1]
We realized we were more than just friends. We were family. Time has a way of giving people the opportunity to grow and understand ... Working with Burt is not a bit different from how it used to be. He expects me to deliver and I can. He knows what I'm going to do before I do it, and the same with me. That's how intertwined we've been.[1]
A one-off collaboration headed by Warwick and featuring Gladys Knight, Elton John, and Stevie Wonder, with a different second verse, was released as a charity single in the UK and the US in 1985. The song is in the key of E♭ major.[3] It was recorded as a benefit for the American Foundation for AIDS Research, and raised more than US$3 million for that cause. Warwick, who had previously raised money for blood-related diseases such as sickle-cell anemia, wanted to help combat the then-growing AIDS epidemic because she had seen friends die painfully of the disease.[4] John plays piano and Wonder plays harmonica on the song; the two had previously worked together on 1983's "I Guess That's Why They Call It the Blues".
In the US, the song held the number-one spot of the adult contemporary chart for two weeks, the number-one spot of the soul chart for three weeks, and the top spot of the Billboard Hot 100 for four weeks. It became Billboard's number one single of 1986. It was certified Gold on January 15, 1986, by the Recording Industry Association of America (RIAA). It was 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.
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.[6]

So working against AIDS, especially after years of raising money for work on many blood-related diseases such as sickle-cell anemia, seemed the right thing to do. 'You have to be granite not to want to help people with AIDS, because the devastation that it causes is so painful to see. I was so hurt to see my friend die with such agony,' Warwick remembers. 'I am tired of hurting, and it does hurt.
