If you are into surf style, tomorrow is your chance to see the best of it. The T-shirt maker Mambo is holding a surf jam in conjunction with Surfers Against Sewage at Porthtowan Beach, Cornwall. Mambo, committed to 'surfing and art and music and sex and life and death and questioning the social imperative of game show hosts and just about the whole damned thing', has produced a limited edition T-shirt to raise awareness of ocean pollution - likely to be the one to be seen in down on the beach for the final five minutes of summer.
