Deep in the Heart of Texas
Even Bing Crosby was not immune to the practice of arbitrarily banning tunes. His jazzy song Deep in the Heart of Texas was taken off the radio for having a catchy beat, which is what made it so successful in the first place. The BBC had its share of naysayers once more.
The BBC played the song during a "music while you work" program ten years to the day after the 1942 debut of the song, and chaos erupted. Or, to be more precise, people joined in. The song features a lot of clapping, and it appears that the employees were so engrossed in the music that they stopped what they were doing and joined in, disrupting productivity. The music was swiftly prohibited from being played while working.
A productive worker is a worker with no rhythm, thus it appears that the BBC went all out against any American song that dared feature clapping, whistling, or other distracting sounds that a worker could be tempted to replicate while they were on the clock.
