Which 1991 number one song in the U.S. and UK has the line: "All my pictures seem to fade to black and white"?

The line, "All my pictures seem to fade to black and white", is from the song Don't Let the Sun Go Down on Me" which is a song written by English singer and songwriter Elton John and his lyricist Bernie Taupin. It was originally recorded in 1974 by Elton John for his studio album Caribou. It was released as a single that peaked at number 2 on the Billboard Hot 100 chart and reached number 16 in the UK Singles Chart. The song subsequently found further success in 1991 in a live cover version recorded as a duet between John and George Michael, which reached number 1 in the UK and US.

Elton John stated that the song is about suicidal thoughts he had earlier in his career. The lyrics describe someone who is going nowhere in life, just standing still. People and things are dark and grey; the person feels tired and depressed.

It seems that these feelings were caused by a lover who has left his love due to a dispute. The suicidal person who has lost his love can't put things right.
