Noosa Main Beach is a prime promenade for the fashion-conscious, except at 7am when it belongs to the athleisure and wetsuit wearers, as the health-conscious crowd walk, run, surf, paddle, gossip and sip endless lattes. So it was an oddity when I passed an older man recently wearing a ‘Morning of the Earth’ t-shirt; no one under sixty will get this reference to a cult surf rock movie from 1969.
