When I were but a lad (just pull that sandbag over, would you), we minions of the glorious 390MU Working Party would be transported every day from Seletar to Changi in the back of a Bedford 3-tonner
Mind you, arrival time in Changi village was planned such that we had time for an egg banjo
That brings back memories of Akrotiri 1965-67 when dozens of local coaches (of varying antiquity) transported the married folk to and from their Limassol hirings every day. When KD had to be worn on the first day of "summer" the big coach parks took on the appearance of a flasher's convention with hundreds of chaps clad in blue raincoats and KD shorts.
