The Navy Lark, one of radio's longest running laughter-makers, kept the nation on the crest of a comic wave from 1959 to 1977. All at sea in the Senior Service were conniving Petty Officer Jon Pertwee, silly-ass Sub-Lieutenant Leslie Phillips and the constantly bemused Dennis Price as 'Number One'. Below decks Ronnie Barker was just about working his passage as (Un)Able Seaman 'Fatso' Johnson.
Jump on deck and join them once more as Phillips is considered for promotion, unrest rises aboard Troutbridge, 'Old Thunderguts' has domestic problems with his wife and 'Number One' faces a terrible decision on whether or not to disclose a hush-hush matter to the crew.
