“I Was Kaiser Bill’s Batman” was a novelty one-hit wonder by a chap who called himself Whistling Jack Smith. Actually it wasn’t one chap, it was two. Trumpeter John O’Neill (who also more famously whistled the melody to Ennio Morricone’s theme from The Good, The Bad and The Ugly) actually recorded the song, but it was a fellow named Billy Moeller (stage name Coby Wells) who you saw on the album cover and strutting around like an idiot on the pop shows of the day.
Billy was the brother of Tommy Moeller of Unit 4 + 2 (a one-hit wonder in their own right with a song called “Concrete and Clay”) and a roadie for the band. The songwriters, Roger Cook and Roger Greenaway would late pen “Long Cool Woman in a Black Dress” for The Hollies.
The name Whistling Jack Smith was a take-off of ‘20s era singing sensation Whispering Jack Smith. The song’s original title was “Too Much Birdseed,” which is still good, but not nearly as good as “I Was Kaiser Bill’s Batman,” eh?
Regarding the video, can you imagine how humiliating a thing like this would be to do for money? Pretending to whistle? (Whistle-syncing?) And he’s not even the one doing the whistling in the first place, making him like the Milli Vanilli of whistle-syncing. Working in a McDonald’s would be a less embarrassing gig!
