Jarvis Cocker: "I've had anxiety dreams over Pulp gigs"
Jarvis Cocker says he's had sleepless nights ahead of Pulp's comeback gigs.
The indie band announced they were reforming last November, and play their first headline set at Spain's Primavera Festival this weekend.
"I've had a few anxiety dreams already," the singer told BBC 6 Music's Steve Lamacq.
"The favourite is usually wandering through a festival, then looking at your watch and realising you should have been on stage 10 minutes ago."
He added: "I've not had the one of being naked on stage yet."
Pulp, who scored hits with Common People and Do You Remember The First Time, have been on hiatus since 2002.
Cocker went on to record solo material and established himself as a radio broadcaster, while other band members pursued careers in production and film-making.
The frontman said they had resisted getting back together "for a long time", but jokingly denied being offered "a duffle bag full of money" to reform.
Guitarist Mark Webber explained that the death of a mutual friend had prompted the band to reconvene.
"I always thought we'd do something together again eventually, but when he died, I realised [we] should maybe grasp that opportunity," he said.
"I think that had a lot to do with it," agreed Jarvis Cocker. "You suddenly realise you can't take things for granted."
The group's most famous live show came at Glastonbury in 1995.
They were drafted in to close the festival after The Stone Roses cancelled at the last minute. The booking came so late that the band were forced to camp as all the local hotels were full.
Nonetheless, they received a rapturous reception, closing with a seven-minute singalong to Common People.
The band also premiered three new songs - Mis-Shapes, Disco 2000 and Sorted For Es and Wizz.
Webber said the lyrics to those songs were only finished the night before, with Cocker "hunched over" in his tent.
Pulp headlined the Pyramid Stage once more in 1998 and played their final gig at Rotherham's Magna Science Centre four years later.
The reunited band play UK festivals including T In The Park, Isle Of Wight and Wireless this summer.
You can hear Pulp speaking exclusively on Steve Lamacq's BBC 6 Music show this Friday, 27 May, from 1600 BST (1500 GMT).
