Rock legends Led Zeppelin have said they may write new songs on the back of their London reunion gig next month.
The band's last original studio album came out 28 years ago
The veteran rock band's guitarist Jimmy Page said he would be "really surprised if there wasn't".
"We're musicians - as we're playing we'll probably be coming up with all manner of things," he told Canadian newspaper The Winnipeg Sun.
"That will be fun. Let's do the O2 show, shall we? And then we'll speak to you afterwards," added the musician.
The band's surviving members, who will reunite for one night only at the London venue on 26 November, announced earlier this week that they would make their entire back catalogue available online.
Page, along with singer Rober Plant and bassist John Paul Jones, will perform together for the first time in 19 years at the tribute concert for late Atlantic Records boss Ahmet Ertegun.
Led Zeppelin's last original studio album release was In Through The Out Door in 1979.
They scored a string of consecutive chart-topping albums from 1969-79, including the second and third parts of their eponymous trilogy and 1975's Physical Graffiti.
Their only UK single release came in 1997 when classic track Whole Lotta Love made number 21 in the charts.
