Queen guitarist Brian May says it might be a struggle to condense the band's back catalogue into a festival set.

The group will headline the 2016 Isle of Wight festival with singer Adam Lambert.

It will be the band's first UK festival show in their long history, with Queen also set to play events in Sweden and Portugal next year.

Speaking to the Daily Express, May said he is already questioning how to distill Queen's catalogue into festival slots.

He said: "The problem with the Isle of Wight is how do we get all the hits in? We shall see.

"It's a very exciting thing to be part of because we've never done a festival before."

Queen and Lambert toured the world in 2014 and 2015.

The band performed in regions such as North America and Europe.
