Whistling Jack Smith

Whistling Jack Smith is not a real person. A record called "I Was Kaiser Bill's Batman" was recorded and released in 1967 and was performed by various studio musicians, including John O'Neill of the Mike Sammes Singers, who did the whistling. "Whistling Jack Smith", a play on a real singer named Whispering Jack Smith, was chosen as a front for the performers, but when the record became an unexpected hit, the producer needed someone to "perform" as Whistling Jack Smith on TV and other media outlets.
