Top pop band McFly will officially launch Longleat’s Fireworks extravaganza on Friday from an open-top bus, after a day spent visiting the animals.

Although they won’t be performing, the boys will be visiting the safari park’s meerkat enclosure, and getting hands-on with a variety of creepy crawlies, before the 6.30pm launch.

McFly’s Danny Jones, Tom Fletcher and Dougie Poynter will be without drummer Harry Judd, who is currently starring in this year’s Strictly Come Dancing.

The spectacular evening display, Fireworks Go Wild, has a wildlife theme, and will be performed again tomorrow (Saturday) from 6pm, with a bonfire.

Longleat’s Melissa Burns said: “We’re absolutely delighted to have the boys from McFly here to spend the day with us and it’s already caused quite a stir among our staff.

“They were looking for somewhere to go for a great day out and contacted us to see if they can come and visit and launch the fireworks, it is very exciting for us.

“They are getting a VIP tour so it isn’t a signing opportunity, but people may catch a glimpse of them around the park on the day.

“For them to be on hand to officially set off our fireworks show will make it a really special event for everyone.”

The display is designed by internationally renowned pyrotechnics firm Dragonfire.

Special Twilight Tickets are available for the displays which allow entry to Longleat after 4pm for just £5 per person.
