A different beat

Yep, more music stuff :-)
This may seem like a strange thing - using slower "old and boring" music to get rid of unwanted individuals. However, it is nothing new - and it works!
Any good bouncer/doorman, bartender, DJ or band will tell you how the music may directly affect the mood.
In places I have worked, music has been used as a way to end fights, alert the bouncers, turn away unwanted individuals and reduce the level of "aggression". So yes - the Cliff thing is still good :-)

Story:
UK -- A traditional funfair has discovered a novel way of scaring off gangs of hoodies - by playing Cliff Richard records.

The travelling steam fair was plagued by gangs of yobs who used to intimidate customers, until they accidentally discovered the hoodie repelling properties of Sir Cliff.

Now the fair uses the records the keep gangs of teenagers at bay, and have also discovered that the music actually attracts a new breed of customers - even if they are mainly old ladies.

A representative said: "We cater mainly for families, but we had a lot of young teenage gangs of hoodies around looking intimidating and putting all the families off, and they never spent any money either. They just scared good customers away."

"We usually play a lot of original 50s rock and roll, but the other day I accidentally put on a Cliff Richard B side called Travelling Light. All the hoodies pulled horrible faces and walked off."

"The next time, we tried it again, and it worked, so we bought a few more. The slow ones like Living Doll and The Young Ones are the most effective. Summer Holiday worked as well, but we try to stick to ones from the 50s to keep the feel of the fair authentic."

"We don't play them all the time because it wouldn't be fair on the staff - it's only when we feel the hoodies are starting to outnumber the families. We play some of the older records, and that gets rid of them."
