This will be the band's third performance at the event and each time they have been a huge hit with the crowd.
McFly have also previously switched on Leeds Christmas lights.

They are expected to perform songs from their new album, Radioactive, released July 21, as well as some old favourites.

Also added to the line-up is Sandi Thom, who had a big hit with I wish I was a Punk Rocker (With Flowers in my Hair) last year.

The line-up also includes Scouting for Girls, Alphabeat and David Jordan.

The event is organised by Leeds City Council in partnership with 96.3 Radio Aire.

Sunday's event will be preceded on the Saturday by Opera in the Park, which will feature the orchestra of Opera North and the Leeds Philharmonic Chorus, who will perform classics including music by Puccini, Verdi, Mozart and Bizet.

Tickets for both events can be obtained from the City Centre Box Office at The Carriageworks, Leeds Visitor Centre and the receptions at Radio Aire and Magic 828.

Opera in the Park tickets can also be obtained from a number of local libraries, including Morley.

However, BreezeCard members can request tickets online at www.breezeleeds.org.uk/party, and disabled people can make a request by post by sending a stamped, addressed envelope to: Events Team, Leeds Town Hall, The Headrow, Leeds, LS1 3AD.
