“Shambolic” traffic management at the Michael Buble concert at Waddesdon Manor saw thousands of angry music fans miss the show completely last night.

The Grammy-award winning ‘Haven’t Met You Yet’ singer was set to perform to thousands of his fans in a spectacular outdoor show at the picturesque Rothschild property – but traffic jams outside the venue meant a large majority of people couldn’t even get in to watch him.

And there has been a warning that the “farcical” scene could be repeated tonight, as Senbla – the events company responsible for organising the live shows – is expecting thousands more people to descend on Waddesdon to see McFly perform.

Hundreds of fuming fans – many who had travelled from across the country especially to see the singer - took to Twitter to complain about the “chaotic” scenes outside Waddesdon last night, which left thousands out of pocket having seen none of the live show.

“Never coming to see you again Buble, after yesterday’s Waddesdon Manor shambles,” Philip Wolfe said.

“2.5 hours in a jam, no signs, no traffic management, no info. Reached car park (hundreds still behind) – it was over.”

Another said: “I am so disappointed about last night’s concert, we came all the way from Dorset to see your show and due to the completely awful organisation at the venue spent over 2.5 hours trying to get in and park, missing most of your show. The organisers should be ashamed!”

“Absolutely disgusting that we didn’t get to see Michael Buble at Waddesdon Manor last night due to poor event management! We were stuck on the A41 in traffic for three hours between Aylesbury and Waddesdon and missed the whole concert. This was my mother-in-law’s Christmas present,” another added.

Thames Valley Police Aylesbury Vale said they had been made aware of the traffic issues before and after the concert, saying: “We have spoken to the organisers and will endeavour to work with them to avoid issues for future events.

“We are made aware of these events in advance but it is rare we police them as there are tried and tested processes in place in respect of event management.

"The traffic management plan clearly needs to be reviewed following tonight’s events.”

A spokesman for Senbla said of last night's issues: "We are urgently investigating with the traffic management company responsible what happened with part of the route into the main site last night.

"We understand some people were affected by the congestion and we are further investigating the reasons behind this and will be issuing another update in due course which can provide more clarity.”

In response to tonight's McFly concert, the spokesman added: "We have held meetings with the traffic management team this morning to ensure that we have extra stewards and signage in place to assist drivers in entering and leaving the side.

"We kindly ask that drivers please follow the signage and directions from stewards at all times and not use their vehicle Sat Nav when parking.”
