Headliners The Cure are set to play "upbeat" songs at Electric Picnic, but could change their set list moments before they go on stage.
Band leader Robert Smith said with their line up changing to include former David Bowie collaborator Reeves Gabrels, they are playing more of their upbeat tracks, but he could slip a few "epic" songs into the set depending how he feels just before they go on stage.
He told NME magazine: "Some of the songs we haven't played in a while will be back in the set. And generally the more sort of upbeat songs.
"I don't know whether we'll be doing any epics. I kind of doubt it, although you never know. A few beers and I shall probably change the set list five minutes before we go on."
Smith, 53, also said he's looking forward to checking out new music at the Reading and Leeds festivals this week, but anyone who doesn't want to watch his band's headline set must be a "fool".
He added: "I'm sure that shall come away from it having seen acts that I would never have dreamed of listening to and probably will be raving about in six month's time. I think there's nothing to stop you having a wonderful weekend even if you don't like The Cure, which I'm sure there will be people there that won't.
"They're fools, but what can you do?"
The Cure are set to headline on the Main Stage of Electric Picnic on Saturday, August 1. Tickets for the three-day arts and music festival are available from Ticketmaster.
