Ticket buyers for the RAF in Concert tour, which gets under way in Norwich tonight, are being warned against purchasing from secondary ticket websites.

Event organiser, the Royal Air Force Charitable Trust Enterprises (RAFCTE) is telling people to check the concert venue's official box office before paying more than necessary on ticket resale websites.

The warning comes after RAFCTE was made aware of concert tickets being resold for £93 – which is nine times their face value.

Ed Sheeran was forced to cancel 10,000 sales when tickets for his tour were discovered on resale websites at inflated prices, including one pair of tickets that were being sold for an eye-watering cost of £174,000.

Marketing director Shane Bellamy said: 'We're keen for as many people as possible to come along and enjoy the impressive sounds of the RAF Bands while we celebrate 100 years of the Royal Air Force. We would urge anyone interested in attending to purchase tickets at the correct value from the official website or directly from the relevant venue.

'Seats are still available so there is simply no need to pay anything above the face value of the ticket and you can buy with confidence that funds raised will go towards the excellent work of the Royal Air Force Charitable Trust'.

The RAF in Concert tour, which starts with tonight's show at the Theatre Royal, marks the end of a series of events that have been staged around the UK this year serving to commemorate the centenary of the air force.

The concert is the last official event marking the centenary and will feature rousing military marches, big band numbers and timeless classical pieces, accomplished musicians from the RAF's principal bands.

Audiences will be treated to classic military tunes including the The Dambusters March and Spitfire Fugue as well as the big band sound of Glenn Miller's In the Mood and Keep 'em Flying. Also taking to the stage will be RAF vocalists Corporal Matthew Walker and Senior Aircraftwoman Philippa Hobbs performing some hugely popular songs including Come Fly With Me, Mr Blue Sky, and Miss Otis Regrets.

The concert tour includes: September 29: Theatre Royal, Norwich; October 3: Royal Concert Hall, Glasgow; October 4: Sage Gateshead, Gateshead; October 19: Wales Millennium Centre, Cardiff; October 23: Waterfront, Belfast; October 27: Royal Concert Hall, Nottingham; October 28: Marlowe Theatre, Canterbury; October 31: Bridgewater Hall, Manchester.
