Having just finished a run of concerts, Cliff will be back in due course!
Hope you enjoyed seeing him!
Whenever Cliff publishes dates, and whatever booking information is provided, it's always recommended that you purchase your tickets from the listed and recommended suppliers.
There are always going to be people out there who want your money and don't care if you don't get into a concert as the ticket they've sold you is fake, or that they've sold you a hugely over-priced ticket as they know you desperately want to see Cliff.
Also, remember that publishing your tickets online as a picture on facebook also give those nasty people out there the chance to use your tickets bar code number to create frauds, so hide that information and don't be the person to turns up to find that your ticket has been 'used'.
Don't let them win.
