When Elton John wrote Your song, it had an immediate success ; so Elton John happened to go to Holland to appear on a TV show. However, instead of performing the song, the TV show wanted to do... a clip. Here's an extract of Elton John's autobiography Me, Elton John :
"We went to Holland to appear on a TV show and instead of getting us to perform, they insisted on making a film of me in a park, miming 'Your song' into a microphone while surrounded, for some reason, by actors pretending to be paparazzi taking my photograph. They still show it on TV sometimes. I look absolutely furious, like I'm about to punch somebody - a fairly accurate representation of how I felt, but not really the ideal delivery for a tender ballad about blossoming love."
Here is the famous clip : https://www.youtube.com/watch?v=CrznwpD-2tk
