"Wonderful Tonight" is a song written by Eric Clapton. It was included on Clapton's 1977 album Slowhand and released as a single the following year. Clapton wrote the song about Pattie Boyd, and it is mentioned in her autobiographical book Wonderful Tonight: George Harrison, Eric Clapton, and Me.
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."
In 1988, Clapton appeared in the Nelson Mandela 70th Birthday Tribute concert as a guest guitarist for Dire Straits. The group became his backing musicians for a surprise performance of "Wonderful Tonight" during their set.
