Let’s go back to 1984 to watch Paul McCartney perform on a London street corner where NO ONE RECOGNIZES HIM!
In that year, he did a movie called “Give My Regards to Broad Street”, which was basically about a fictional day in his life.
The movie bombed. But it did have a cool scene where Paul performed with a guitar on a London street corner, and no one recognized him.
Apparently, the scene was LEGIT. They actually put Paul on the street, and the people he was performing to were NOT actors.
Of course, he wasn’t trying to look like, or even sound like, himself. His hair was ruffled, and his clothes were disheveled.
He was performing “Yesterday”, but it was a different, folk version of it.
