"(Everything I Do) I Do It for You" is power ballad by Canadian singer-songwriter Bryan Adams. Written by Adams, Michael Kamen, and Robert John "Mutt" Lange, it was featured on two albums, firstly the soundtrack album from the 1991 film Robin Hood: Prince of Thieves released on July 2, 1991, and then on Adams's sixth album, Waking Up the Neighbours (1991) released September 24, 1991.
The song was an enormous chart success internationally, reaching the number-one position on the music charts of at least nineteen countries, notable exceptions in the Western World being Italy (number three) and Spain (number four). It is particularly notable for its success in the United Kingdom, where it spent sixteen consecutive weeks at number one on the UK Singles Chart, the longest uninterrupted run ever on that chart as of 2021. It also topped the Europe-wide sales chart for eighteen continuous weeks. In the United States, it topped the Billboard Hot 100, which combines radio airplay and sales, for seven weeks, but stayed at number one for seventeen consecutive weeks on the sales-only chart. It went on to sell more than 15 million copies worldwide, making it Adams's most successful song, and one of the best-selling singles of all time. The song has been covered by hundreds of singers and artists around the world.
Based on orchestral music by Kamen, the song was written in London, U.K. at the studio Adams was working at in 1990, and he and Lange wrote it in 45 minutes, recording it the following March, and releasing it three months later.
