Jammie dodgers.
Had to look it up. Now I want one.
The all British music radio show London Calling has a gag that the host can’t talk because of eating jammie dodgers during songs. Show once a week on Saturday nights has British invasion through current British music. Digestives are mentioned in biographies of Eric Clapton and others——they all like them, apparently.
