His Independent obituary recalls a nice anecdote:
Bowen displayed great wit in private and was much admired as an after-dinner speaker. Lord Hooson, a former leader of the Liberal Party in Wales, recounts a tale about the first visit the then Lord Chief Justice Parker made to Wales in the 1970s. Bowen remarked to the distinguished guest: "You are about to meet a Welsh jury for the first time. Beware. Welsh juries are against sin - but not dogmatically so."
