I first saw footage of The Beatles’ famous 1969 rooftop concert as a child, growing up far, far away from 3 Savile Row where it took place and all that it signified. One of band’s renditions of Get Back from that set was shown on Top Of Pops and I was knocked back by the cool bravura of it. Now, someone has posted the full 42 minutes on YouTube and these days, of course, part of the fascination lies in the scenes of London and Londoners of the time. Listen, watch and wonder. And savour the man with the trilby and pipe skipping up a ladder for a better view.
