Traditional comic Marlow regatta with fast forwarded sequence which makes it even messier.
Full title reads: "MARLOW".
River Thames at Marlow. Various shots of the crowds and boats gathered for the annual Marlow Regatta. Various shots of the races - broomsticks, paddles, pans are used to move the boats.
Tires hanging on ropes. In this race each member of the crew has to get through tyre head first and return to boat to continue the race. Some contestant in water and boats turned over. Follows the fast forwarded sequence - everything is much faster then run at normal speed and the voiceover is just a funny noise. People in boats rowing very fast, boats moving and turning around - just mess.
