Was watching the old 1968 hey Jude promo film the other day also known as right now and I was wondering if it was lip synced seeing as I could clearly see john lennon playing an epiphone casino when in the audio I hear acoustic guitar.
My question is was it lip-synced along with a backing track and if so, was the present audio combined? Because in the beginning they are playing around some theme song (clearly live) for David Frost. When you lip-sync for promo films, do you pretend to play your instrument and sing while the track blasts in the speakers, or do you play along and then they take out the audio from your play along, and paste the original track over? If it's mimed along with the backing track blasting over the speakers and the audio isn't removed, how do you make those drums sound normal,seing as drums are quite loud? A Combination of two normal sounds that play the same thing create a chorus effect, do they not? Why can't I hear that on "Hey Jude"'s 1968 Promo Film? Also at the end, you can hear clapping from the controlled audience so what's going on here?
The video in question:Help, please, can't get this question off my mind.
