becaus John Bonham, in natural deference to Zep's mythos, took the chance to add his own 'visual idyll' sequence to the Song Remains The Same movie. No vikings, no Tolkien, no black magic or dweller at the threshold,but HAVING A PINT, WALKING, RIDING A BIKE, using a pneumatic drill on some BRICKS, and driving a fuckoff drag car. Oh, and wearing wellies.
