In film Night Shift; composed by husband and wife. Not to be confused with Paul Williams' song, cut by B.J. Thomas in '72 and Deniece Williams' (not related).
Dionne's n°1 US was first envisioned as a duet between her and Stevie Wonder. Actress Elisabeth Taylor witnessed the recording, listened to the lyrics and as she was an active anti-AIDS activist, got the idea (and songwriter Carole Bayer-Sager's permission) to detour the proceeds to the American Foundation for AIDS Research. That's when Elton John and Gladys Knight were asked and accepted to join in. This hit marked the end of a 10 year hiatus since Burt Bacharach & Dionne Warwick's last successful collaboration (in a series of no less than 33).
