Elton John and the improvised song about your new oven

This video has been circulating the rounds on the web for a few years, but it dates back longer than that. (You can never really tell from the ageless hairpieces that Sir Elton has on.) This is from a 1997 special called An Audience with Elton John, and this segment, featuring actor Richard E. Grant in a star-packed audience, shows how clever the star is with an improvised melody.
