But they are now appearing for sale on Internet ticket agency sites — and they are going for £138 to £262 for a single ticket.

A pair of tickets for the Caird Hall gig will also set fans back £229 to £399 a pair on eBay.

An eBay spokesperson said, “It is a fair and reasonable consumer right for the purchaser of a ticket to resell that ticket unless the resale would be unlawful.”

Several ticket agencies are also cashing in.

Website ticketpolice.com was selling individual tickets for the Caird Hall gig at £138 for the cheapest price, with the Perth show costing £202 per brief.

The agency’s top price for a single ticket was £262.

World Ticket Shop was selling briefs at £174 each for both shows.

Viagogo was slightly cheaper at £134 per ticket for Dundee and £120 for Perth.

There was also a steady flow of tickets for sale on auction site eBay for the sold out Dundee gig.

A pair of tickets was being offered at Buy It Now price for £229, £245, £285 and £399.

The Perth show was slightly cheaper with prices ranging from £150 to £206.

Senior promoters and figures within the music industry have long called for touting to be made illegal, but the Government has always stopped short of such a measure.

Tickets for football matches cannot be resold.

With more and more fans desperate to get into gigs, demand often exceeds supply, so creating a marketplace ripe for exploitation by ticket agencies and touts.

Fans often now find themselves either ripped off buying tickets or unable to buy tickets at all, because so many are snapped up by touts looking to profit on their resale.

Some estimates suggest as many as 40% of tickets are now being sold on via the Internet and although secondary selling websites claim to provide a service for fans unable to use tickets, thousands of tickets can be found for sale at many times face value as soon as popular events sell out and often well before.

Comedian Billy Connolly last appeared in Dundee in 2005.

The Big Yin’s sold out Scottish tour will also take in Perth, Edinburgh, Aberdeen and Glasgow.

Connolly last performed in Dundee in 2005, but famously brought a BBC camera crew to the city in 1994 as part of his World Tour of Scotland.

He then complemented a comic concert at the Caird Hall with a straight reading of William McGonagall’s The Tay Bridge Disaster at the top of the Law, where he was beset by a blizzard.

Connolly began his stage career as an accomplished banjo player in the band The Humblebums, but the jokes he told between songs soon outweighed the music and he has since toured all over the world with his eclectic mix of stand-up and strumming.

With nearly four decades in the entertainment industry under his belt, Connolly has also turned his hand to acting, famously starring opposite Dame Judy Dench in the 1997 movie Mrs Brown.
