Silent Disco Walking Tour sensation Guru Dudu leads his guests through the Grassmarket during the Fringe

Council chief are facing growing calls to curb the singing and dancing antics of large groups amid claims they are “creating a hazard to themselves, other pedestrians and passing traffic.”

The Edinburgh Old Town Association (EOTA) and the Old Town Community Council are demanding strict enforcement of where and when they can operate amid claims that some “unrelated gatherings” are now “bulldozing” people out of the way.

City council chiefs have admitted that the growing popularity of silent discos has “compounded” problems with overcrowding during peak festival periods. Congestion concerns have led to the drawing up of radical road closures, relocated bus services and suspended taxi ranks this year.

However the authority insists it is powerless to bring many operators under control due to a loophole in the law which means they do not need a street trading licence if they only sell tickets online.

A new EOTA bulletin states: “Silent discos are a fairly new idea for extracting money from tourists and making them behave like complete idiots.

“Groups of gullible punters are fitted out with earphones through which disco music is played to them. A group leader encourages them to sing and dance along to music being pumped into their ears. Some groups are well-managed. Others are a hazard to themselves, other pedestrians and passing traffic.”

A separate dossier for the authority compiled by the community council states: “Some of these represent huge unregulated ‘public gatherings’ of people that completely take over footpaths, bulldozing regular users out of the way. Tours over say 10 people, need licensed and regulated in number and timing.”

Bill Cowan, planning and transport secretary at the community council, said: “The problems with silent discos have got dramatically worse over the last couple of years, especially the unregulated ones.

“They are anything but silent. You can’t hear any music, but that doesn’t stop the participants from yelling, shouting and screaming as you would at a real disco. If you’re at a disco you’re in an enclosed space and under supervision. These people are prancing along pavements a metre wide. If you meet 40 of them pushing a shopping trolley up a hill it’s really serious. The council needs to figure out a way to control them.”

EOTA treasurer Rosemary Mann said: “A silent disco is a misnomer. The one thing they’re not is silent. Although the guide speaks to the group through headphones, they shout and clap along.

“They’re incredibly noisy and disruptive, far more so than ghost tours. They’re also anti-social. They can block a complete street corner.”
