Amprocks is now heading for a sell out with organisers urging fans to buy tickets in advance or risk disappointment.
Sales this week surpassed last year’s record of 3,100 with no let-up during June.
And with just two weeks to go there are fears no tickets will be available on the night.
Madchester legends Happy Mondays headline sat Ampthill Park on July 4 – supported by Fenech Soler – sparking “unprecedented interest” in tickets for the big night, which kicks off the three-day Ampthill Festival.
“We haven’t seen anything like this before,” said Amprocks Chairman Ian Scarr.
“We thought last year would be hard to beat but 2014 has surpassed all expectations and more.
“There are still some tickets remaining but if sales are maintained at the current rate – and we always expect a sharp increase in the week before - there will be a lot of disappointed people.
“We have had interest from all over the country so we urge locals that if you haven’t got a ticket yet, please buy one as soon as possible.”
Tickets – priced £18 - are available from dr barbers in Dunstable St, Ampthill or online from http://amprocks.eventbrite.com and www.ampthillfestival.co.uk/amprocks
