On September 8th, 1968, David Frost did premier the song “Hey Jude” in Britain on his show “Frost On Sunday.” His filmed sequence begins with The Beatles running through an ad libbed version of David Frost’s television theme music entitled “By George! It’s David Frost Theme” (written by George Martin). This spurs the host to exclaim: “Magnificent! A perfect rendition! Ladies and Gentlemen, there you see the greatest tea-room orchestra in the world. It’s my pleasure to introduce now, in their first live appearance for goodness knows how long in front of an audience, The Beatles.” (It wasn’t live, of course.) On the show, this segues directly into the beginning of “Hey Jude” but, in actuality, The Beatles begin a few seconds of a humorous rendition of Elvis Presley’s hit “It’s Now Or Never” which was caught on film and has become available on various sources
