On 7 September 1976, Clapton wrote "Wonderful Tonight" for Boyd while waiting for her to get ready to attend Paul and Linda McCartney's annual Buddy Holly party. Of "Wonderful Tonight", Boyd would say: "For years it tore at me. To have inspired Eric, and George before him, to write such music was so flattering. 'Wonderful Tonight' was the most poignant reminder of all that was good in our relationship, and when things went wrong it was torture to hear it."
It was also featured in "The One With the Proposal Part 2" (18 May 2000) in season 6 of the famous TV show Friends. It shows Monica and Chandler dancing to it at the end of the episode after getting engaged.
Clapton and Steve Winwood performed an acoustic version of the song during their 2011 tour in Japan.
Also in 1989, a Spanish cover was recorded by Argentinian singer JAF.
Filipino musician and entrepreneur Ramon "RJ" Jacinto covered the song for his 2000 album, The Ultimate RJ Bistro Collection. It also later appeared on his 2005 compilation album, Rock 'n Roll Classics.
